Using oral tegafur/uracil (UFT) plus leucovorin as adjuvant chemotherapy in stage II colorectal cancer: a propensity score matching study from Taiwan. BMC Cancer 2023; 23:900. [PMID: 37749535 PMCID: PMC10518963 DOI: 10.1186/s12885-023-11310-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Accepted: 08/17/2023] [Indexed: 09/27/2023] Open
Abstract
BACKGROUND Early-stage colorectal cancer had excellent outcomes after curative resection, typically. However, a perplexing survival paradox between stage II and stage III was noted. This paradox could be influenced by the administration of routine postoperative adjuvant chemotherapy and the presence of high-risk factors in stage II CRC. The objective of the study was to investigate the influence of high-risk factors on patients with stage II CRC and assess the efficacy of oral tegafur/uracil (UFT) plus leucovorin as adjuvant chemotherapy for stage II CRC patients. METHODS A retrospective study was conducted using propensity score matching at a single medical institution. A total of 1544 patients with stage II colorectal cancer who underwent radical surgery between January 2004 and January 2009 were included. The intervention used was tegafur/uracil plus leucovorin as adjuvant chemotherapy. The main outcome measures were disease-free survival and overall survival. RESULTS After propensity score matching, 261 patients were included in three groups: no-treatment, half-year treatment, and one-year treatment. The clinical characteristics of each group tended to be more consistent. The Cox proportional hazard models showed that tegafur/uracil treatment or not was a significant independent factor for oncological outcome. Kaplan-Meier analysis also showed significantly better disease-free survival and overall survival. Further investigation revealed that tegafur/uracil duration was an independent factor for oncological outcome. While the survival curve did not reach statistical significance, the one-year UFT treatment group demonstrated the best treatment trend. CONCLUSIONS This study suggests that tegafur/uracil plus leucovorin is a feasible adjuvant chemotherapy regimen for patients with stage II colorectal cancer after curative surgical treatment. Prolonged tegafur/uracil plus leucovorin treatment for 12 months showed a trend towards better outcomes in patients with stage II colorectal cancer.

The optimal time of starting adjuvant chemotherapy after curative surgery in patients with colorectal cancer. BMC Cancer 2023; 23:422.

Abstract
BACKGROUND Postoperative adjuvant chemotherapy (AC) is now well-accepted as standard for high-risk stage II and stage III colorectal cancer (CRC) patients, however the optimal time to initiate AC remains elusive. METHODS A comprehensive literature search was performed using the PubMed and Embase databases. The Hazard ratio (HR) with the corresponding 95% confidence interval (CI) was used as an effect measure to evaluate primary endpoints. All analyses were conducted using Stata software version 12.0 with the Random-effects model. RESULTS A total of 30 studies were included in our study. Upon comparison on overall survival (OS), we identified that delaying the initiation of AC for > 8 weeks after operation was significantly associated with poor OS (HR: 1.37; 95% CI: 1.27-1.48; P < 0.01). The poor prognostic value of AC delay for > 8 weeks was not undermined by subgroup analysis based on region, tumor site, sample size and study quality. No obvious differences were observed in survival between AC within 5-8 weeks and ≤ 4 weeks (HR: 1.03; 95% CI: 0.96 -1.10; P = 0.46). Moreover, two studies both highlighted that the survival benefit of AC was still statistically significant when AC was applied 5-6 months after surgery compared with the non-chemotherapy group. CONCLUSIONS Delaying the initiation of AC for > 8 weeks after surgery was significantly associated with poor OS. AC started within 8 weeks after surgery brought more benefits to CRC patients. There were no obvious differences in survival benefits between AC within 5-8 weeks and ≤ 4 weeks. Compared to patients not receiving AC after surgery, a delay of approximately 5-6 months was still useful to improve prognosis.

Prognostic Impact of Early Treatment and Oxaliplatin Discontinuation in Patients With Stage III Colon Cancer: An ACCENT/IDEA Pooled Analysis of 11 Adjuvant Trials. J Clin Oncol 2023; 41:803-815. [PMID: 36306483 DOI: 10.1200/jco.21.02726] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 07/08/2022] [Accepted: 08/30/2022] [Indexed: 11/06/2022] Open
Abstract
PURPOSE Oxaliplatin-based adjuvant chemotherapy in patients with stage III colon cancer (CC) for 6 months remains a standard in high-risk stage III patients. Data are lacking as to whether early discontinuation of all treatment (ETD) or early discontinuation of oxaliplatin (EOD) could worsen the prognosis. MATERIALS AND METHODS We studied the prognostic impact of ETD and EOD in patients with stage III CC from the ACCENT/IDEA databases, where patients were planned to receive 6 months of infusional fluorouracil, leucovorin, and oxaliplatin or capecitabine plus oxaliplatin. ETD was defined as discontinuation of treatment and EOD as discontinuation of oxaliplatin only before patients had received a maximum of 75% of planned cycles. Association between ETD/EOD and overall survival and disease-free survival (DFS) were assessed by Cox models adjusted for established prognostic factors. RESULTS Analysis of ETD and EOD included 10,447 (20.9% with ETD) and 7,243 (18.8% with EOD) patients, respectively. Compared with patients without ETD or EOD, patients with ETD or EOD were statistically more likely to be women, with Eastern Cooperative Oncology Group performance status ≥ 1, and for ETD, older with a lower body mass index. In multivariable analyses, ETD was associated with a decrease in disease-free survival and overall survival (hazard ratio [HR], 1.61, P < .001 and HR, 1.73, P < .001), which was not the case for EOD (HR, 1.07, P = .3 and HR, 1.13, P = .1). However, patients who received < 50% of the planned cycles of oxaliplatin had poorer outcomes. CONCLUSION In patients treated with 6 months of oxaliplatin-based chemotherapy for stage III CC, ETD was associated with poorer oncologic outcomes. However, this was not the case for EOD. These data favor discontinuing oxaliplatin while continuing fluoropyrimidine in individuals with significant neurotoxicity having received > 50% of the planned 6-month chemotherapy.

Abstract
INTRODUCTION Late adjuvant chemotherapy (aCT) administration after colectomy (> 56 days) is known to be associated with impaired prognosis. We aim to identify risk factors associated with late aCT, especially the travel time between patients' home and hospital. METHOD We performed a retrospective monocentre cohort study. Patients included had a colectomy for a stage III or "high risk" stage II colon cancer between 2009 and 2015 performed at a French university hospital. Risk factors for late aCT were identified using a fractional polynomial logistic regression. RESULTS Ninety-four patients were included. The risk of late aCT was associated with travel time length, emergent colectomy, the need for scheduled care before aCT, and length of time between colectomy and postoperative multidisciplinary meeting advising aCT. CONCLUSION Our study suggests that, in patients with colon cancer, factors unrelated to disease severity and complexity could be associated with a higher risk of late aCT.

Original Research: Long-Term Prognosis After ST-Elevation Myocardial Infarction in Patients with a Prior Cancer Diagnosis. Cardiol Ther 2021; 11:81-92. [PMID: 34724192 PMCID: PMC8933597 DOI: 10.1007/s40119-021-00244-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Accepted: 10/21/2021] [Indexed: 12/24/2022] Open
Abstract
Introduction It is unknown how long-term prognosis after ST-elevation myocardial infarction (STEMI) in patients with a prior cancer diagnosis is impacted by cancer-related factors as diagnosis, stage, and treatment. We aimed to assess long-term survival trends after STEMI in this population to evaluate both cardiovascular and cancer-related drivers of prognosis over a follow-up period of 5 years. Methods In this retrospective single-center cohort study, patients with a prior cancer diagnosis admitted with STEMI between 2004 and 2014 and treated with primary percutaneous coronary intervention (PCI) were recruited from the STEMI clinical registry of our institution. Results In the 211 included patients, the cumulative incidence of all-cause death after 5 years of follow-up was 38.1% (N = 60). The cause of death was predominantly malignancy-related (N = 29, 48.3% of deaths) and nine patients (15.0%) died of a cardiovascular cause. After correcting for age and sex, a recent cancer diagnosis (< 1 year relative to > 10 years, HRadj 2.98 [95% CI: 1.39–6.41], p = 0.005) and distant metastasis at presentation (HRadj 4.02 [1.70–9.53], p = 0.002) were significant predictors of long-term mortality. While maximum levels of cardiac troponin-T and creatinine kinase showed significant association with mortality (resp. HRadj 1.34 [1.08–1.66], p = 0.008; HRadj 1.36 [1.05–1.76], p = 0.019), other known determinants of prognosis after STEMI, e.g., hypertension and renal insufficiency, were not significantly associated with survival. Conclusions Patients with a prior cancer diagnosis admitted with STEMI have a poor survival rate. However, when the STEMI is optimally treated with primary PCI and medication, cardiac mortality is low, and prognosis is mainly determined by factors related to cancer stage.

Abstract
The impact of cycle completion rates of oxaliplatin-based adjuvant chemotherapy for stage III colon cancer in real-world practice is unknown. We assessed its impact, and that of treatment modification, on 3-year cancer-specific mortality. Four thousand one hundred and forty-seven patients with pathological stage III colon cancer undergoing major resection from 2014 to 2017 in the English National Health Service were included. Chemotherapy data came from linked national administrative datasets. Competing risk regression analysis for 3-year cancer-specific mortality was performed according to completion of <6, 6-11, or 12 5-fluoropyrimidine and oxaliplatin (FOLFOX) cycles, or <4, 4-7, or 8 capecitabine and oxaliplatin (CAPOX) cycles, adjusted for patient, tumour and hospital-level characteristics. Median age was 64 years. Thirty-two per cent of patients had at least one comorbidity. Forty-two per cent of patients had T4 disease, and 40% had N2 disease. Compared to completion of 12 FOLFOX cycles, cancer-specific mortality was higher in patients completing <6 cycles [subdistribution hazard ratios (sHR) 2.17; 95% CI 1.56-3.03] or 6-11 cycles (sHR 1.40; 95% CI 1.09-1.78) (P < .001). Compared to completion of 8 CAPOX cycles, cancer-specific mortality was higher in patients completing <4 cycles (sHR 2.02; 95% CI 1.53-2.67) or 4-7 cycles (sHR 1.63; 95% CI 1.27-2.10) (P < .001). Dose reduction and early oxaliplatin discontinuation did not impact mortality in patients completing all cycles. Completion of all cycles of chemotherapy was associated with improved cancer-specific survival in real-world practice. Poor prognostic factors may have affected findings, however, patients completing <50% of cycles had poor outcomes. Clinicians may wish to facilitate completion with treatment modification in those able to tolerate it.

Abstract
The management of locally advanced rectal cancer has grown in both complexity and quality since the first proctectomy. What once was a malignancy with a fairly consistent treatment algorithm for decades, a recent paradigm shift in the care of these patients has led to a more personalized, multidisciplinary approach with variations in timing, sequence, duration, and potential exclusion of multimodality therapies. This review summarizes the most important evidence behind these developing overarching concepts to provide a context for this paradigm shift.

Abstract
PURPOSE Comprehensive Geriatric Assessment (CGA) can identify health problems in older persons. In addition, CGA includes intervention towards the identified problems. With follow up, more problems may be identified and the interventions can be adjusted. We wanted to compare CGA with or without tailored follow-up in a randomised design. PATIENTS AND METHODS Patients 70+ years referred for oncology treatment with four primary tumour sites. Participants were randomised 1:1 to either control group with no follow-up or intervention group with a tailored follow-up by a multidisciplinary team. Primary outcome was adherence to cancer treatment. Secondary outcomes were daily life activities, physical performance and hospitalisation. RESULTS In total, 363 participants were randomised. After randomisation only 301 were planned to receive specific cancer treatment. Median age was 75 years. Among the 301 participants, 52% of control group vs. 61% of intervention group completed treatment. Risk Rate (RR): 1.16 (95% Confidence Interval (CI): 0.95-1.42), p = .14. The impact varied between the included tumour-sites, p < .01. We found no difference in 90 days physical performance or daily life activities between groups. During the study period, 55% of controls vs. 47% in the intervention group were admitted to hospital, RR: 0.86 (95%CI: 0.69-1.07), p = .19. CONCLUSION In frail and vulnerable patients with cancer, a tailored follow-up on CGA showed no differences in ability to complete initially planned cancer treatment. The impact varied between the included tumour sites. We did not find any impact of tailored follow-up on daily life activities, physical performance or hospitalisation.

Abstract
PURPOSES Although adjuvant chemotherapy (AC) has been established as a standard of treatment for advanced rectal cancer, there is no guideline regarding the timing of AC initiation. In this study, we aimed to evaluate the oncologic outcome of early AC initiation and clarify the ideal time to AC among rectal cancer patients receiving preoperative chemo-radiotherapy (preCRT). METHODS The medical records of 719 patients who underwent curative resection followed by AC for rectal cancer were analyzed retrospectively. Data distributions were compared according to the calculated cut-off for AC initiation, survival results, and chemotherapy-induced toxicity. Additionally, patients were divided into two groups according to preCRT status and compared with respect to differences in the optimal time to AC. RESULTS Overall, a cut-off time point of 20 days after surgery for AC initiation was identified as the optimal interval; this yielded a significant difference in disease-free survival but no significant difference in AC toxicity. In the cut-off analysis of patients treated without preCRT, 19 days was identified as the optimal time to AC. However, for patients treated with preCRT, no significant value affected the survival outcome. CONCLUSIONS Earlier initiation of AC (within approximately 3 weeks) was associated with better oncological outcomes among patients with rectal cancer. Additionally, the optimal timing of AC was unclear among patients who received preCRT; this might be attributable to an undetermined role of AC after preCRT or the effects of complications such as anastomotic leakage.

Abstract
BACKGROUND Partnered status is an independent predictor of clinical outcomes, including overall survival, among patients with cancer. However, the mechanisms by which partnered status impacts survival are not fully understood and to the authors' knowledge the associations between partnered status and the specific attributes of chemotherapy have not been studied to date. METHODS The current study was an observational study of patients with resected American Joint Committee on Cancer (AJCC) stage III colon cancer diagnosed from 2008 through 2015 and recruited from an academic cancer center and 2 large community oncology practices. Outcome measures were specific attributes of adjuvant chemotherapy. Partnered status (partnered vs unpartnered) was the primary independent variable. Bivariate comparisons between independent variables and the primary outcomes were performed. Associations between partnered status and the outcomes also were analyzed using multivariable generalized estimating equations using a logit link. RESULTS Data were collected from 436 patients. Of these patients, approximately 65% were from community oncology practices. Approximately 62% were partnered (married or living with a partner), and approximately 86% received adjuvant chemotherapy. Among these individuals, 87% received multiagent chemotherapy and 65% completed 6 months of therapy. Partnered patients were found to have a higher odds of completing chemotherapy (odds ratio, 1.98; 95% CI, 1.04-3.77). CONCLUSIONS In this innovative investigation of the associations between partnered status and specific attributes of curative-intent chemotherapy, approximately 35% of patients terminated chemotherapy early. Having a partner increased the odds of completing therapy, which may be one mechanism through which having a partner improves disease-specific outcomes among patients with colon cancer. Identifying those aspects of partner support that can be reproduced with community or clinical personnel may help unpartnered patients to complete the recommended course of curative-intent chemotherapy.

Abstract
Background A fixed 8-cycle oxaliplatin and capecitabine (XELOX) regimen has been the standard adjuvant therapy for patients with stage III colon cancer. However, completing the full-cycle of oxaliplatin is often associated with severe neurotoxicity. To spare patients from the toxic effects, without comprising the required efficacy, we evaluated the safety and efficacy of a modified XELOX (mXELOX) adjuvant chemotherapy regimen with 6 cycles of oxaliplatin and a full cycle of capecitabine. Methods We retrospectively analyzed 330 eligible patients with stage III colon cancer who underwent curative tumor resection followed by mXELOX, standard XELOX or unfinished XELOX adjuvant chemotherapy between December 2007 and April 2015. Associated prognostic factors were investigated and their disease-free survival (DFS) and overall survival (OS) rates were also determined and compared among the different regimen groups. Results Compared with the standard XELOX group, the mXELOX group had lower total incidence rates of neurotoxicity (39.3% vs. 76.2%, P < 0.001), leucopenia (53.6% vs. 69.8%, P = 0.017) and thrombocytopenia (38.1% vs. 56.3%, P = 0.011). The standard XELOX and mXELOX adjuvant chemotherapy regimens presented with comparable 3-year DFS rates (86.3% vs. 89.2%; P = 0.838) and 3-year OS rates (92.7% vs. 97.6%; P = 0.227). Compared to unfinished XELOX chemotherapy, the oncologic benefits of the mXELOX regimen were greater for patients with T4 tumors (3-year DFS: Hazard ratio [HR], 2.184; 95% confidence interval [CI], 1.051–4.540; P = 0.036; 3-year OS: HR, 4.529; 95% CI 1.245–16.479; P = 0.022) and for high-risk patients (3-year DFS: HR, 1.962; 95% CI 0.964–3.993; P = 0.044; 3-year OS: HR, 4.193; 95% CI 1.182–14.874; P = 0.026). Conclusions The mXELOX adjuvant chemotherapy presented a comparable survival benefit and lower incidence of toxicity than standard XELOX chemotherapy. It could be an alternative treatment for high-risk patients with operated stage III colon cancer.

Abstract
IMPORTANCE The results from the recent International Duration Evaluation of Adjuvant Therapy (IDEA) collaboration have led some clinicians to adopt shorter durations of adjuvant chemotherapy for patients with stage III colon cancer. The extent to which these findings are supported by other data is unknown. OBJECTIVE To conduct a systematic review and meta-analysis of randomized and observational studies investigating the association between the duration of adjuvant chemotherapy and survival among individuals diagnosed as having stage II and III colon cancer (PROSPERO protocol CRD42018108711]). DATA SOURCES Abstracts published in English between 2003 and 2018 within the MEDLINE, Embase, CENTRAL, and CINAHL databases were reviewed by 2 authors. Also searched were conference proceedings and the indexes of high-impact oncology journals. STUDY SELECTION Studies were excluded if they did not present original data; focused on animal populations, on cancers in sites other than the colon, or on patients with stage 0, I, or IV disease; did not examine a 5-flourouracil-based monotherapy or combination therapy; or did not evaluate the association between treatment duration and survival. The search identified 2341 articles, from which 2 randomized trials and 20 observational studies were included in the meta-analysis. DATA EXTRACTION AND SYNTHESIS This study followed the PRISMA and MOOSE reporting guidelines. The risk of bias was assessed by 2 authors using the Cochrane and Risk of Bias in Nonrandomized Studies of Interventions (ROBINS-I) tools. The results were synthesized using a random-effects model. MAIN OUTCOMES AND MEASURES The primary and secondary outcomes were overall survival and disease-free survival, respectively. It was hypothesized a priori that 3 months of chemotherapy would be as effective as 6 months of chemotherapy. RESULTS Twenty-two studies were included in the meta-analysis, representing 43 671 patients. The inclusion of patients with stage II disease or with rectal cancer was identified as a source of heterogeneity. After restricting the analysis to patients with stage III colon cancer, there was no association between the duration of chemotherapy and overall survival among studies involving FOLFOX (leucovorin calcium [folinic acid], fluorouracil, and oxaliplatin) or CAPOX (capecitabine plus oxaliplatin) regimens (hazard ratio [HR], 0.80; 95% CI, 0.58-1.09). Among studies focused exclusively on monotherapy, the standard 6-month regimen relative to a 3-month regimen was associated with improved survival (HR, 0.59; 95% CI, 0.52-0.68). CONCLUSIONS AND RELEVANCE Shortened durations of chemotherapy may reduce survival among patients with stage III colon cancer prescribed monotherapy but not a combination regimen.

Abstract
Although it is recommended to initiate postoperative chemotherapy for colon cancer within 8 weeks after surgery, the feasibility and impact of initiating chemotherapy before discharge after surgical resection has not been investigated.Patients with stage II-IV colon cancer who received postoperative chemotherapy were dichotomized into early (chemotherapy initiation before discharge) and control (chemotherapy initiation after discharge) groups. A multivariable logistic regression model was used to determine factors associated with delayed chemotherapy, defined as more than 6 or 8 weeks after surgery.From January 2004 to December 2012, of 729 patients with stage II-IV colon adenocarcinoma, 555 patients (76.1%) underwent postoperative chemotherapy. Of them, 181 (32.6%) patients were included in the early group. Time to initiation of chemotherapy was significantly shorter in the early group than in the control group (14.9 days vs 31.5 days, P < . 001). Multivariate analysis revealed that tumor stage and chemotherapy initiation strategy (odds ratio 8.4; 95% confidence interval, 1-66, P = .041) were independent predictors of delayed initiation of chemotherapy at more than 8 weeks. There was no difference in the completion rate of planned chemotherapy cycles between the 2 groups (P > .05).The strategy of initiating chemotherapy before discharge after surgery is safe and feasible and might reduce the potential delay in chemotherapy initiation in patients with colon cancer.

Abstract
(1) Background: The optimal timing of adjuvant chemotherapy (CT) in gastrointestinal malignancies is still a matter of debate. For colorectal cancer, it is recommended to start post-operative treatment within eight weeks. The objective of this study was to assess the clinical effects of starting adjuvant CT within or after 6–8 weeks post-surgery in colorectal, gastric, and pancreatic cancer. (2) Methods: MEDLINE, EMBASE, and the Cochrane Library were searched in December 2018. Publications comparing the outcomes of patients treated with adjuvant CT administered before (early) or after (delayed) 6–8 weeks post-surgery for colorectal, gastric, and pancreatic cancer were identified. The primary endpoint was overall survival (OS). (3) Results: Out of 8752 publications identified, 34 comparative studies assessing a total of 141,853 patients were included. Meta-analysis indicated a statistically significant increased risk of death with delayed CT (>6–8 weeks post-surgery) in colorectal cancer (hazard ratio (HR) = 1.27, 95% confidence interval (CI) 1.21–1.33; p <0.001). Similarly, for gastric cancer, delaying adjuvant CT was associated with inferior overall survival (HR = 1.2, 95% CI 1.04–1.38; p = 0.01). Conversely, the benefit of earlier CT was not evident in pancreatic cancer (HR = 1, 95% CI 1–1.01; p = 0.37). Conclusions: Starting adjuvant CT within 6–8 weeks post-surgery is associated with a significant survival benefit for colorectal and gastric cancer, but not for pancreatic cancer.

Delivery of adjuvant chemotherapy among stage III colon cancer patients at a public versus private hospital in New York City. Cancer Causes Control 2017; 29:253-260.

Abstract
PURPOSE Prior studies of timeliness of adjuvant chemotherapy (AC) initiation in stage III colon cancer have suggested longer time to AC at public compared with private hospitals. Few studies have explored differences in AC completion. We investigated whether timely initiation and completion of AC differed between a public and private hospital, affiliated with the same academic institution in a large, urban setting. METHODS We conducted a retrospective cohort study of stage III colon cancer patients who had surgery and AC at the same medical center between 2008 and 2015, either at its affiliated public hospital (n = 43) or private hospital (n = 79). We defined timely initiation as receiving AC within 60 days postoperatively, and completion as receiving ≥ 75% of planned AC. Univariate and stepwise multivariable logistic regressions were used to identify factors associated with AC delivery. RESULTS Median number of days to AC was significantly greater among patients at the public (53, range 31-231) compared with the private hospital (43, range 25-105; p = 0.002). However, the percentage of patients with timely AC initiation did not differ substantially by hospital (74 vs 81%, p = 0.40). In multivariable analysis, age (OR 0.95/year, 95% CI 0.91-0.99) and laparoscopic versus open surgery (OR 5.65, 95% CI 1.92-16.62) were significant factors associated with timely AC initiation. Moreover, AC completion did not differ significantly between public (83.7%) and private (89.9%) hospital patients (p = 0.32). CONCLUSIONS The proportions of patients with timely initiation and completion of AC were similar at a public and private hospital affiliated with a large, urban medical center. Future research should investigate how specific system-level factors help alleviate this expected difference in timely care delivery.

Abstract
BACKGROUND Selecting elderly people with colorectal cancer (CRC) for adjuvant chemotherapy is challenging. Comprehensive geriatric assessment (CGA) can help by classifying them according to their frailty profile. The supposed benefit of chemotherapy is on the basis of the rate of treatment adherence. In this study we evaluated tolerance and adherence to tailored-dose adjuvant therapy on the basis of CGA in a cohort of older patients with high-risk stage II and stage III CRC. PATIENTS AND METHODS This was a prospective study in 193 consecutive patients aged 75 years or older. On the basis of CGA results, we classified patients as fit, medium fit, or unfit, administering standard therapy, adjusted treatment, and best supportive care, respectively. We recorded planned chemotherapy, toxicity, and completion of the treatment. A logistic multivariate analysis was carried out. RESULTS Seventeen (15%) of the 141 candidates for chemotherapy (n = 86 fit and n = 55 medium fit) refused treatment; associated factors included polypharmacy (odds ratio [OR], 5.34; 95% confidence interval [CI], 1.55-18.40) and rectal location (OR, 5.61; 94% CI, 1.45-21.49). Of the 105 (74%) patients receiving chemotherapy, 20 (27%) fit and 4 (13%) medium fit patients experienced Grade 3 to 4 toxicity (P = .11) without association to explanatory variables. Approximately 55% of patients treated with chemotherapy received at least 80% of the planned dose (55% fit and 58% medium fit patients; P = .7). Factors associated with completion of chemotherapy were the absence of toxicity (OR, 7.67; 95% CI, 2.41-24.43) and social support (OR, 2.29; 95% CI, 0.08-1.04). CONCLUSION CGA is useful for selecting elderly patients for adjuvant chemotherapy, adapting the dose to their frailty profile, and identifying adherence-related factors amenable to modification through CGA-based interventions.

Abstract
For many women with non-metastatic breast cancer, adjuvant chemotherapy prevents recurrence and extends survival. Women who discontinue chemotherapy early may reduce those benefits, but little is known about what predicts early discontinuation. We sought to determine prospectively the rate and reasons for early discontinuation of adjuvant chemotherapy in women with breast cancer. We conducted a prospective cohort study among three U.S. health care organizations. Of 1158 women with newly diagnosed non-metastatic breast cancer, 2006-2010, we analyzed 445 (38.4 %) patients who initiated standard adjuvant chemotherapy as defined by accepted guidelines. We interviewed patients at baseline and twice during treatment regarding sociodemographic/psychosocial factors and treatment decision-making and collected clinical data. They were categorized according to the number of cycles required by the chemotherapy regimen they had initiated. The outcome was early discontinuation (<80 % of planned cycles). Of patients analyzed, 392 (88.1 %) completed the prescribed therapy. The strongest predictor was receipt of a regimen entailing >4 cycles of therapy (18.1 % for longer regimens, 7.4 % for 4 cycles) (odds ratio [OR] 2.59, 95 % CI 1.32-5.08), controlling for race, age, stage, hormone receptor status, social support, optimism, spirituality, stress, and physical symptoms. Higher levels of psychological symptoms on the Memorial symptom assessment scale also increased the odds of early discontinuation (OR 1.92, 95 % CI 0.998-3.68). The large majority of patients who initiated adjuvant chemotherapy for breast cancer completed their prescribed regimens, but early discontinuation was associated with lengthier regimens and, with borderline statistical significance, for those with psychological side effects.

Abstract
A multimodality disciplinary approach is paramount for the management of locally advanced rectal cancer. Over the last decade, (chemo)radiotherapy followed by surgery plus or minus adjuvant chemotherapy has represented the mainstay of treatment for this disease. Nevertheless, robust evidence suggesting the optimal timing and sequence of therapies in this setting has been overall limited. A number of questions are still unsolved including the length of the interval between neoadjuvant radiotherapy and surgery or the timing of systemic chemotherapy. Interestingly, emerging data support the contention that altering sequence or timing or both of the components of this multimodality approach may provide an opportunity to implement treatment strategies that far better address the risk and expectations of individual patients. In this article, we review the available evidence on timing of therapies in the multidisciplinary treatment of locally advanced rectal cancer and discuss the potential implications for routine practice that may derive from a change of the currently accepted treatment paradigm.

Factors Affecting Use and Delay (≥8 Weeks) of Adjuvant Chemotherapy after Colorectal Cancer Surgery and the Impact of Chemotherapy-Use and Delay on Oncologic Outcomes. PLoS One 2015; 10:e0138720. [PMID: 26381146 PMCID: PMC4575146 DOI: 10.1371/journal.pone.0138720] [Citation(s) in RCA: 43] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2015] [Accepted: 09/02/2015] [Indexed: 11/20/2022] Open
Abstract
Purpose To evaluate factors affecting the use and delay ≥8 weeks of adjuvant chemotherapy and the impact of chemotherapy use and delay on survival. Methods Between 2005 and 2012, consecutive patients with stage II and III colorectal cancer who were treated with major curative resection were enrolled. Results Among 750 patients with stage II (n = 318) and III (n = 432) disease, 153 (20.4%) did not receive chemotherapy. Among 597 patients with adjuvant chemotherapy, 31 (5.2%) began chemotherapy 8 weeks or more after surgery. Factors associated with not receiving chemotherapy were: age ≥80 years (hazard ratio [HR] = 5.2), American Society of Anesthesiologists score ≥3 (HR = 1.9), underlying cerebrovascular disease (HR = 1.7), stage II disease (HR = 2.0), presence of postoperative complications (HR = 2.2), or intensive care unit admission (HR = 2.4). Factors associated with chemotherapy delay ≥8 weeks were: male sex (HR = 4.2), rectal primary cancer (HR = 5.4), or presence of postoperative complications (HR = 2.5). Independent prognostic factors for overall survival included TNM III stage (HR = 2.04) and chemotherapy delay ≥8 weeks (HR = 0.39) or <8 weeks (HR = 0.22). Independent prognostic factors for recurrence-free survival were TNM III stage (HR = 2.26) and chemotherapy delay <8 weeks (HR = 0.35). Conclusions Postoperative complications were associated with both lack of and delayed chemotherapy. Timely initiation of chemotherapy, defined as <8 weeks, was a favorable prognostic factor for overall and recurrence-free survival. To increase the proportion of patients receiving chemotherapy and timely initiation of chemotherapy, surgical complications should be minimized after curative resection.

Abstract
BACKGROUND Currently available data suggest that delaying the start of adjuvant chemotherapy in colon cancer patients has a detrimental effect on survival. We analysed which factors impact on the timing of adjuvant chemotherapy and evaluated the influence on overall survival (OS). PATIENTS AND METHODS Stage III colon cancer patients who underwent resection and received adjuvant chemotherapy between 2008 and 2013 were selected from the Netherlands Cancer Registry. Timing of adjuvant chemotherapy was subdivided into: ⩽ 4, 5-6, 7-8, 9-10, 11-12 and 13-16 weeks post-surgery. Multivariable regressions were performed to assess the influence of several factors on the probability of starting treatment within 8 weeks post-surgery and to evaluate the association of timing of adjuvant chemotherapy with 5-year OS. RESULTS 6620 patients received adjuvant chemotherapy, 14% commenced after 8 weeks. Factors associated with starting treatment after 8 weeks were older age (Odds ratio (OR) 65-74 versus < 65 years 1.3 (95% confidence interval (CI): 1.14-1.58); OR ⩾ 75 versus < 65 years 1.6 (1.25-1.94)), emergency resection (OR 1.8 (1.41-2.32)), anastomotic leakage (OR 8.1 (6.14-10.62)), referral to another hospital for adjuvant chemotherapy (OR 1.9 (1.36-2.57)) and prolonged postoperative hospital admission (OR 4.7 (3.30-6.68)). Starting 5-8 weeks post-surgery showed no decrease in OS compared to initiation within 4 weeks (Hazard ratio (HR) 5-6 weeks 0.9 (0.79-1.11); HR 7-8 weeks 1.1 (0.91-1.30)). However, commencing beyond 8 weeks was associated with decreased OS compared to initiation within 8 weeks (HR 9-10 weeks 1.4 (1.21-1.68); HR 11-12 weeks 1.3 (1.06-1.59); HR 13-16 weeks 1.7 (1.23-2.23)). CONCLUSION Our data support initiating adjuvant chemotherapy in stage III colon cancer patients within 8 weeks post-surgery.

Abstract
BACKGROUND AND OBJECTIVES In stage III colonic cancer, time from surgery to start of adjuvant chemotherapy may influence survival. In this study, we evaluated the effect of timing of adjuvant therapy on survival. METHODS Database study from the Danish Colorectal Cancer Group's national database. Data on patients with stage III colonic cancer operated between January 1, 2005 and August 31, 2012 were retrieved. Perioperative variables, surgical modality, and time to adjuvant therapy (<4, 4-8, or >8 weeks) were evaluated and Cox regression was performed to identify factors influencing survival. RESULTS The final population included 1,827 patients scheduled for adjuvant chemotherapy. Adjuvant therapy started within 4 and 8 weeks improved survival when compared to start later than 8 weeks (HR [95%CI]: 1.7 [1.1-2.6]; P = 0.024 and 1.4 [1.07-1.8]; P = 0.013, respectively), whereas there was no significant difference in survival with start after 4 versus 8 weeks (1.2 [0.8-1.8]; P = 0.37). CONCLUSIONS Survival increased when adjuvant therapy was started within 8 weeks after surgery for stage III colonic cancer.

Effect of Adjuvant FOLFOX Chemotherapy Duration on Outcomes of Patients With Stage III Colon Cancer. Clin Colorectal Cancer 2015; 14:262-8.e1. [PMID: 26123496 DOI: 10.1016/j.clcc.2015.05.010] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2015] [Revised: 05/24/2015] [Accepted: 05/29/2015] [Indexed: 01/22/2023]
Abstract
BACKGROUND Studies have demonstrated that patients with stage III colon cancer who receive adjuvant FOLFOX (5-fluorouracil and oxaliplatin) chemotherapy experience an improved disease-free (DFS) and overall survival (OS). However, the magnitude of benefit among patients who discontinue FOLFOX early is not well known. We sought to examine the rate of FOLFOX treatment completion, determine the factors associated with adherence, and explore the relationship between duration of FOLFOX treatment and survival. PATIENTS AND METHODS We analyzed patients diagnosed with stage III colon cancer from 2006 to 2010 and initiated at least 1 cycle of adjuvant FOLFOX at any 1 of 5 regional cancer centers in British Columbia. Logistic regression models were constructed to determine the clinical factors associated with treatment completion, which was defined as receipt of ≥ 10 cycles of FOLFOX. Kaplan-Meier methods and Cox regression that accounted for known prognostic factors were used to evaluate the relationship between early FOLFOX discontinuation and DFS and OS. RESULTS We identified 616 patients: median age of 62 years (range, 26-80), 321 (52%) men, 536 (87%) with T3/4 tumors, and 245 (40%) with N2 disease. Among them, 183 (30%) received < 10 and 433 (70%) received ≥ 10 cycles. Adjusting for covariates, female sex and the absence of obstruction or perforation were each associated with receiving ≥ 10 cycles of FOLFOX (odds ratio [OR], 1.61; 95% confidence interval [CI], 1.12-2.32; P = .01 and OR, 1.82; 95% CI, 1.08-3.05; P = .02, respectively). In multivariate analyses, early discontinuation of FOLFOX did not affect DFS or OS (hazard ratio [HR], 1.16; 95% CI, 0.82-1.63; P = .40 and HR, 1.07; 95% CI, 0.70-1.61; P = .76, respectively). CONCLUSION Early discontinuation of FOLFOX was not associated with differences in survival outcomes, lending support to clinical trials that are under way to evaluate the efficacy of shorter durations of therapy.

Abstract
BACKGROUND The survival benefit of administering adjuvant chemotherapy (AC) in colorectal cancer is well established, as is the impact of its timing. Although various factors have been associated with treatment delay, their implications remain controversial. We determined clinicopathological factors associated with delay in transition to AC via systematic review and meta-analysis. METHODS Studies assessing factors for delay in initiating AC were identified from MEDLINE, EMBASE, and Cochrane Databases. Studies were included only if relevant clinicopathological factors were adequately described and appropriate comparative groups were balanced. For each study, the odds ratio (OR) and 95 % confidence interval (CI) were estimated, regarding response to early versus delayed AC initiation. RESULTS We identified 15 eligible studies involving 67,537 patients. Twelve studies were multicentre studies and three were single-center cohort studies. Meta-analysis demonstrated age >75 years [4 studies, OR = 1.44 (95 % CI 1.32-1.58)], marital status-single [3 studies, OR = 1.32 (95 % CI 1.20-1.44)], low socioeconomic status (SES) [7 studies, OR = 1.67 (95 % CI 1.32-2.12)], worse comorbidity status [5 studies, OR = 1.47 (95 % CI 1.14-1.90)], low tumour grade [7 studies, OR = 1.06 (95 % CI 1.02-1.11)], prolonged length of stay [3 studies, OR 2.37 (95 % CI 2.10-2.68)], and readmission [3 studies, OR = 3.23 (95 % CI 1.66-6.26)] were significant predictors of delayed initiation of AC. Laparoscopy compared to an open surgical approach was a significant predictor of earlier AC initiation [5 studies, OR = 0.70 (95 % CI 0.51-0.97)]. CONCLUSIONS Laparoscopy is associated with earlier initiation of AC, encouraging its increased adoption. Social isolation and low SES merit consideration of approaches that counter the lack of social support and deprivation to improve cancer outcomes.

Abstract
BACKGROUND Previous studies have evaluated the impact of time to adjuvant chemotherapy (AC) on survival in early-stage colon cancer. However, the optimal time to adjuvant chemotherapy (TTAC) in rectal cancer remains unclear. The objective of this study was to identify an optimal TTAC and determine its prognostic effect in stage 2 to 3 rectal cancer. METHODS Patients with stage 2 to 3 rectal cancer treated with preoperative chemoradiation and postoperative AC between 1999 and 2008 were included. Predetermined time points of 4, 6, 8, and 12 weeks from date of surgery were analyzed. Cut-point analysis was then used to determine an optimal TTAC, and overall survival at the identified cut-point was evaluated. RESULTS A total of 328 eligible patients were identified with a median age of 61 years (range 22-85 years), 70% male, and 75% stage 3 disease. The median TTAC was 7.0 weeks. Initiation of AC at 6 weeks from date of surgery was associated with a significant survival benefit (hazard ratio 0.52, 95% confidence interval 0.31-0.90, P = .017), while no significant association was seen at 4, 8 or 12 weeks (P > .05). The cut-point analysis identified an optimal TTAC of 5.6 weeks association with improved survival compared to those with a TTAC greater than 5.6 weeks (hazard ratio 0.42, 95% confidence interval 0.22-0.82, P = .0087). This cut-point was also found to be a significant prognostic factor in multivariable analysis (P = .04) adjusted for Eastern Cooperative Oncology Group performance status, age, gender, stage, margin status, and grade. CONCLUSIONS This study suggests that initiation of AC within an earlier time frame is associated with improved overall survival.

Abstract
AIM The study included investigation of factors determining suboptimal adjuvant chemotherapy of patients diagnosed with Stage III colon cancer. METHOD All 606 patients diagnosed with Stage III colon cancer between 2006 and 2008 in the western part of the Netherlands were included. Patient [gender, age, comorbidity and socio-economic status (SES)], tumour (location, stage and grade) and treatment (emergency surgery, laparoscopic surgery, reoperation, hospital stay and multidisciplinary meeting) factors were examined in logistic regression analyses predicting a complicated postoperative period and omission, delay and discontinuation of adjuvant chemotherapy. RESULTS Overall, 27% of all patients experienced a complicated postoperative period, which was independently associated with emergency surgery, older age, multiple comorbidity, male gender and poor tumour grade. Of patients who survived this period, 60% received chemotherapy. Chemotherapy was omitted more often in women, the elderly and in patients with Stage IIIB, reoperation, prolonged hospital stay and (borderline) after open surgery. Of patients who received chemotherapy, 86% started within 8 weeks after surgery. Patients with a higher SES, reoperation and prolonged hospital stay had a higher probability of a delayed start. Sixty-seven per cent of patients completed their chemotherapy. For women, elderly patients and patients with prolonged hospital stay a higher probability of discontinuation was noted. CONCLUSION Age was the most important predictive factor for receiving adjuvant chemotherapy. However, at all ages, complicated postoperative recovery negatively influenced the administration of chemotherapy to Stage III colon cancer patients, as well as a timely start and completion of chemotherapy.

Abstract
Background Delayed chemotherapy is associated with inferior survival in stage III colon and stage II/III rectal cancer patients, but similar studies have not been performed in stage II colon cancer patients. We investigate the association between delayed and incomplete chemotherapy, and the association of delayed chemotherapy with survival in stage II colon cancer patients. Patients and Methods Patients (age ≥66) diagnosed as stage II colon cancer and received chemotherapy from 1992 to 2005 were identified from the linked SEER–Medicare database. The association between delayed and incomplete chemotherapy was assessed using unconditional and conditional logistic regressions. Survival outcomes were assessed using stratified Cox regression based on propensity score matched samples. Results 4,209 stage II colon cancer patients were included, of whom 73.0% had chemotherapy initiated timely (≤2 months after surgery), 14.7% had chemotherapy initiated with moderate delay (2–3 months), and 12.3% had delayed chemotherapy (≥3 months). Delayed chemotherapy was associated with not completing chemotherapy (adjusted odds ratio (OR): 1.33 (95% confidence interval: 1.11, 1.59) for moderately delayed group, adjusted OR: 2.60 (2.09, 3.24) for delayed group). Delayed chemotherapy was associated with worse survival outcomes (hazard ratio (HR): 1.75 (1.29, 2.37) for overall survival; HR: 4.23 (2.19, 8.20) for cancer-specific survival). Conclusion Although the benefit of chemotherapy is unclear in stage II colon cancer patients, delay in initiation of chemotherapy is associated with an incomplete chemotherapy course and poorer survival, especially cancer-specific survival. Causal inference in the association between delayed initiation of chemotherapy and inferior survival requires further investigation.

Abstract
BACKGROUND Adjuvant chemotherapy started more than 56 days after colon cancer resection has been associated with lesser overall survival among patients with stage iii colon cancer. The objective of the present population-based study was to determine, in referred patients with resected stage iii colon cancer, factors associated with delayed time to adjuvant chemotherapy (ttac), defined as more than 56 days from the date of surgery. METHODS Eligible patients had been diagnosed with stage iii colon cancer and had received at least 1 cycle of adjuvant chemotherapy at one of the four regional cancer treatment sites during 2008-2009. Prognostic and treatment information was prospectively collected through the BC Cancer Agency's GI Cancers Outcomes Unit, and Charlson comorbidity score was retrospectively determined by chart review. Chi-square and Wilcoxon rank-sum tests were used to measure associations between the timing of adjuvant chemotherapy and select prognostic and treatment variables. RESULTS Median ttac from surgery for the 395 included patients was 58 days, with 54% of the patients receiving adjuvant chemotherapy beyond the recommended 56 days. On multivariate analysis, only treatment at the highest-volume site was independently associated with delayed ttac. Comorbidity index, age, performance status, T stage, tumour location, and oral chemotherapy (compared with intravenous) were not independently associated with delayed ttac. Delays were observed during each interval associated with the patient's transition from surgery to first cycle of adjuvant chemotherapy. CONCLUSIONS More than half the patients failed to receive adjuvant chemotherapy within the recommended ttac of 56 days. Delayed ttac was associated with process-related delays rather than with patient- or disease-related factors. Efforts to improve timely referral, triage of consultations, and chemotherapy wait lists are required.

Abstract
Colorectal cancer is one of the most commonly diagnosed cancers in men and women in the developed world. Although surgery is the foundation of curative treatment, adjuvant chemotherapy also improves overall and disease-free survival in high-risk stage II and all stage III patients. Research strongly suggests that the timing from surgery to adjuvant chemotherapy is critical, because delays to the start of treatment significantly affect patient outcomes. Both clinical and systemic barriers, such as postoperative complications and institutional wait times, challenge the timely administration of adjuvant chemotherapy. Further research investigating solutions to overcome these barriers is needed.

Impact on Loco-regional Control of Radiochemotherapeutic Sequence and Time to Initiation of Adjuvant Treatment in Stage II/III Rectal Cancer Patients Treated with Postoperative Concurrent Radiochemotherapy. Cancer Res Treat 2014; 46:148-57. [PMID: 24851106 PMCID: PMC4022823 DOI: 10.4143/crt.2014.46.2.148] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2013] [Accepted: 06/20/2013] [Indexed: 12/27/2022] Open
Abstract
Purpose This study was designed to evaluate the impact of radiochemotherapeutic sequence and time to initiation of adjuvant treatment on loco-regional control for resected stage II and III rectal cancer. Materials and Methods Treatment outcomes for rectal cancer patients from two hospitals with different sequencing strategies regarding adjuvant concurrent radiochemotherapy (CRCT) were compared retrospectively. Pelvic radiotherapy was administered concurrently on the first (early CRCT, n=180) or the third cycle of chemotherapy (late CRCT, n=180). During radiotherapy, two cycles of fluorouracil were provided to patients in both groups. In the early CRCT group, median six cycles of fluorouracil and leucovorin were prescribed during the post-CRCT period. In the late CRCT group, two cycles of fluorouracil were administered in the pre- and post-CRCT periods. Results No significant differences in the 5-year loco-regional recurrence-free survival (LRRFS) (92.5% vs. 95.6%, p=0.43) or overall survival and disease-free survival were observed between groups. Patients who began receiving adjuvant treatment later than five weeks after surgery had lower LRRFS than patients who received adjuvant treatment within five weeks following surgery (79% vs. 91%, p<0.01). The risk of loco-regional recurrence increased as the time to initiation of adjuvant treatment was delayed. Conclusion In the current study, treatment outcomes were not significantly influenced by the sequence of adjuvant treatment but by the delay of adjuvant treatment for more than five weeks. Timely administration of adjuvant treatment is deemed important in achieving loco-regional tumor control for stage II/III rectal cancer patients.

Abstract
PURPOSE Timely administration of adjuvant chemotherapy following colorectal resection is associated with improved outcome. We aim to assess the factors which are associated with delay to adjuvant chemotherapy in patients who underwent colorectal resection as part of an enhanced recovery protocol. METHOD A univariate and multivariate analysis of patient data collected as part of a prospectively maintained database of colorectal cancer patients between 2007 and 2012. RESULTS 166 patients underwent colorectal resection followed by adjuvant chemotherapy. Median postoperative hospital stay was 6 days, and time to commencement of adjuvant chemotherapy was 50 days. Longer inpatient stay correlated with increased time to adjuvant chemotherapy (P = 0.05). Factors found to be independently associated with duration of hospital stay and time to commencement of adjuvant chemotherapy included stoma formation (P = 0.032), anastaomotic leak (P = 0.027), and preoperative albumin (P = 0.027). The use of laparoscopic surgery was associated with shorter time to adjuvant chemotherapy but did not reach significance (P = 0.143). CONCLUSION A number of independent variables associated with delay to adjuvant therapy previously not described have been identified. Further work may be required to elucidate the effect that these variables have on long-term outcome.

Abstract
PURPOSE To assess solid cancer treatment feasibility in older patients. METHODS Between 2007 and 2010, 385 consecutive elderly patients (mean age: 78.9 ± 5.4 years; 47.8% males) with solid malignancies referred to two geriatric oncology clinics were included prospectively. We recorded feasibility of first-line chemotherapy (planned number of cycles in patients without metastases and three to six cycles depending on tumor site in patients with metastases), surgery (patient alive 30 days after successfully performed planned surgical procedure), radiotherapy (planned dose delivered), and hormonal therapy (planned drug dose given), and we recorded overall 1-year survival. RESULTS Main tumor sites were colorectal (28.6%), breast (23.1%), and prostate (10.9%), and 47% of patients had metastases. Planned cancer treatment was feasible in 65.7% of patients with metastases; this proportion was 59.0% for chemotherapy, 82.6% for surgery, 100% for radiotherapy, and 85.2% for hormonal therapy. In the group without metastases, feasibility proportions were 86.8% overall, 72.4% for chemotherapy, 95.7% for surgery, 96.4% for radiotherapy, and 97.9% for hormonal therapy. Factors independently associated with chemotherapy feasibility were good functional status defined as Eastern Cooperative Oncology Group performance status <2 (p < .0001) or activities of daily living >5 (p = .01), normal mobility defined as no difficulty walking (p = .01) or no fall risk (p = .007), and higher creatinine clearance (p = .04). CONCLUSION Feasibility rates were considerably lower for chemotherapy than for surgery, radiotherapy, and hormonal therapy. Therefore, utilization of limited geriatric oncology resources may be optimized by preferential referral of elderly cancer patients initially considered for chemotherapy to geriatric oncology clinics.

Abstract
OBJECTIVE The objective of this study was to identify the risk factors for delays in chemotherapy after rectal cancer surgery and evaluate the effects of delayed therapy on long-term outcomes. We also sought to clarify what time frame should be used to define delayed adjuvant chemotherapy. BACKGROUND Postoperative complications have been found to influence the timing of chemotherapy in patients with colon cancer. Delays in chemotherapy have been shown to be associated with worse overall and disease-free survival in patients with colorectal cancer, although the timing of delay has not been agreed upon in the literature. STUDY DESIGN We performed a retrospective review of a prospectively maintained rectal cancer database. Univariate analysis was used to identify risk factors for delayed chemotherapy. Kaplan-Meier curves were generated to compare overall and disease-free survival in patients based on complications and timing of chemotherapy. SETTINGS This study was performed at the University of Wisconsin Hospital, Madison, Wisconsin, between 1995 and 2012. PATIENTS Patients with rectal cancer who underwent proctectomy with curative intent were included in this study. OUTCOME MEASURES Timing of chemotherapy, 30-day complications, and 30-day readmissions were the main outcome measures. RESULTS Postoperative complications and 30-day readmissions were associated with delays in chemotherapy ≥8 weeks after surgery. Patients who received chemotherapy ≥8 weeks postoperatively were found to have worse local and distant recurrence rates and worse overall survival in comparison with patients who received chemotherapy within 8 weeks of surgery. LIMITATIONS The limitations of this study include its retrospective nature and that it was performed at a single institution. CONCLUSIONS We found complications and readmissions to be risk factors for delayed chemotherapy. Patients who received therapy ≥8 weeks postoperatively had worse disease-free and overall survival.

Abstract
PURPOSE Clinical practice guidelines (CPGs) recommend adjuvant chemotherapy after curative-intent surgery for colorectal cancer (CRC). Studies have shown variable rates of adherence to adjuvant therapy CPGs. This study sought to determine the proportion of patients in Nova Scotia receiving CPG-concordant adjuvant chemotherapy within 12 weeks of surgery for CRC in 2001 to 2005, and to identify factors associated with chemotherapy receipt beyond 12 weeks from surgery or chemotherapy nonreceipt. METHODS Patients with stages IIB or III colon or stages II or III rectal cancer who underwent curative-intent surgery in Nova Scotia were identified through the provincial cancer registry and anonymously linked to 14 administrative health databases. Chart review was conducted to obtain chemotherapy data and reasons for chemotherapy nonreceipt. Logistic regression was used to identify factors independently associated with receipt of chemotherapy and meeting the 12-week benchmark (P < .05). RESULTS A total of 1,151 patients were identified, of whom 59% received chemotherapy. Factors predicting chemotherapy receipt were male sex, age < 75 years, no hospital readmission within 30 days of surgery, stage III disease, no prior cancer diagnosis, and rectal cancer. Of the 679 patients who received chemotherapy, 479 (72%) met the 12-week benchmark, with male sex, urban residence, less social deprivation, colon cancer and increased length of hospital stay as significant factors. Of the 472 patients who did not receive chemotherapy, the most common reason for nonreceipt was no consultation with a medical oncologist (53%). CONCLUSION A number of factors influence adherence to adjuvant chemotherapy CPGs for CRC and should be incorporated in future work as novel regimens enter clinical practice.
