Surgical versus non-surgical management for patients with malignant bowel obstruction (S1316): a pragmatic comparative effectiveness trial

Development and validation of a clinical prognosis prediction model for malignant intestinal obstruction: A retrospective cohort study

Malignant bowel obstruction (MBO) is a common and complex condition in clinical practice, which seriously affects the quality of life and prognosis of patients. However, the current lack of effective prognostic models for MBO has greatly limited clinical precision treatment and patient management. Focusing on this issue, this study aims to construct and validate a prognostic model for the overall survival (OS) of MBO patients, providing crucial support for clinical decision - making and improving the prognosis of patients. In this study, 41 items of real - world data from 192 patients in the Affiliated Hospital of Nantong University from January 2022 to January 2024 were collected, including 39 independent variables, survival time, and survival status. Subsequently, the patients were randomly divided into groups at a ratio of 7:3. Predictor variables were screened using the Least Absolute Shrinkage and Selection Operator (LASSO) and multivariate Cox regression, and then a Cox model was constructed. The model was validated using the Concordance index (C - index), time - dependent Receiver Operating Characteristic (ROC) curve, and Decision Curve Analysis (DCA). Finally, a nomogram of the model was created. The study found that significant risk factors affecting patient mortality included chemoradiotherapy (β = - 1.24; HR = 0.29;95%CI, 0.14-0.59), conservative treatment (β = 1.34; HR = 3.81; 95%CI, 1.69-8.55), new cases (β = - 0.96; HR = 0.38; 95%CI, 0.19-0.77), AJCC T stage 4 (β = 2.16; HR = 8.64; 95%CI, 1.47-50.76), red blood cell count (RBC, β = - 0.63; HR = 0.53; ; 95%CI, 0.38-0.80), prothrombin time (PT, β = 0.37; HR = 1.45; ; 95%CI, 1.07-1.97), aspartate aminotransferase (AST, β = 0.01; HR = 1.01; 95%CI, 1.00-1.02), and intestinal necrosis (β = 1.73; HR = 5.62; 95%CI, 1.11-28.27). In the development set, the AUC and C - index values of the prognostic models for 30 - day, 90 - day, and 180 - day are 0.87, 0.94, and 0.92 respectively. In the validation set, the corresponding values are 0.83, 0.96, and 0.89. The results of DCA analysis indicated that the model was reliable and could effectively predict the 30 - day, 90 - day, and 180 - day survival periods of MBO patients. This study successfully constructed and validated a prognostic model for the overall survival of MBO patients. This model identified multiple key prognostic factors and exhibited good predictive performance. It provides important reference for clinicians to predict the survival period of MBO patients and develop personalized treatment plans, and is expected to improve the clinical outcomes of MBO patients.

[Patient safety in palliative surgery]

Palliative surgery aims to improve the quality of life for patients with incurable diseases. This patient group is vulnerable due to the underlying illness, prior treatment and comorbidities, which increase the risk of complications that can negatively impact the course of the disease and quality of life. Palliative surgical interventions often provide effective long-term symptom control but are more invasive than conservative, interventional endoscopic or interventional radiological alternatives. This article exemplary discusses frequent palliative visceral surgical procedures and less invasive alternatives. In practice, a close interdisciplinary collaboration, open and realistic communication, optimized perioperative care and in particular the minimization of cumulative invasiveness are crucial to maximize the quality of life and safety for oncological patients.

Intake and Nutritional Adequacy in Patients With Cancer Diagnosed With Malignant Bowel Obstruction: A Secondary Analysis of a Randomized Trial

BACKGROUND

Malignant bowel obstruction (MBO) is experienced by many with advanced cancer. Patients with MBO cannot eat and may have reduced ability to eat once the acute process has resolved. Sparse data exist to describe oral intake capacity and adequacy of nutrition in patients with MBO. These data are critical to developing effective supportive care nutrition therapy for patients with MBO.

OBJECTIVE

The aim of this study was to describe the ability to consume food and liquids orally, estimating nutritional adequacy of diet in a sample of patients who received surgical or nonsurgical treatment for MBO.

DESIGN

A descriptive secondary data analysis of repeated dietary intake measures from S1316, a pragmatic comparative effectiveness trial of surgical and nonsurgical treatment for MBO. Participant enrollment occurred between 2015 and 2020. Ability to eat was assessed through self-reported telephone survey and intake was estimated using telephone-based 24-hour recalls, applying US Department of Agriculture multipass methodology.

PARTICIPANTS/SETTING

The primary trial was conducted within the SWOG Cancer Research Network and included recruitment sites across the United States and Latin America. Eligible participants were diagnosed with, and hospitalized for, MBO.

MAIN OUTCOME MEASURES

The main outcomes measures were self- or caregiver-reported ability to eat, as well as overall nutrient intake.

STATISTICAL ANALYSIS

Descriptive statistics were used to report patient characteristics, intake, and nutrient adequacy. Nutrient intake was presented by tertiles of gastrointestinal symptom severity and assessed.

RESULTS

Two hundred twenty-one participants were registered; 199 were eligible and included. At week 1, 51% of patients with MBO reported consuming some solid food orally; 34% reported no oral intake; and 13% were on enteral feeding only. For patients alive and responsive to recalls at 13 weeks (n = 57), 82% (n = 47) reported consuming solid food. Compared with recommendations, mean reported intake was inadequate for most nutrients.

CONCLUSIONS

Oral intake is reported in more than one-half of patients diagnosed with MBO. Medical nutrition therapy should be tailored to patient's tolerance for eating and with consideration or patient's desire to address nutritional inadequacies.

Impact of PIPAC-Oxaliplatin on Functional Recovery, Good Days, and Survival in a Refractory Colorectal and Appendiceal Carcinomatosis: Secondary Analysis of the US PIPAC Collaborative Phase 1 Trial

BACKGROUND

Pressurized intraperitoneal aerosolized chemotherapy (PIPAC) is a novel, minimally invasive, safe, and repeatable method to treat carcinomatosis. Evidence regarding the clinical benefit (quality of life and survival) of PIPAC compared with that of conventional standard therapy (ST) is lacking.

METHODS

This is the secondary analysis of the phase 1 US-PIPAC trial for refractory colorectal and appendiceal carcinomatosis. A PIPAC cohort was compared with a retrospective cohort of consecutive patients receiving ST. The primary outcome was number of good days (number of days alive and out of the hospital). The secondary outcomes were overall survival (OS), progression-free survival (PFS), health-related quality of life (HRQoL), and objective functional recovery (daily step count).

RESULTS

The study included 32 patients (PIPAC, 12; ST, 20) with similar baseline characteristics. Compared with the ST cohort, the PIPAC cohort had lower median inpatient hospital stays (> 24 h) within 6 months (0 vs 1; p = 0.015) and 1 year (1 vs 2; p = 0.052) and higher median good days at 6 months (181 vs 131 days; p = 0.042) and 1 year (323 vs 131 days; p = 0.032). There was no worsening of HRQoL after repeated PIPACs. Step counts diminished immediately after PIPAC but returned to baseline within 2-4 weeks. Kaplan-Meier analysis demonstrated a favorable association between receipt of PIPAC and OS (median, 11.3 vs 5.1 months; p = 0.036).

CONCLUSION

Compared with ST, PIPAC was associated with higher number of good days, reduced hospitalization burden, and longer OS without a negative impact on HRQoL with repeated PIPACs. These findings are foundational for evaluation of PIPAC in a randomized clinical trial.

The Impact of Palliative Decompressive Gastrostomy Tube Placement on Patients and Their Caregivers: A Mixed Methods Analysis

BACKGROUND

Palliative decompressive gastrostomy tubes are intended to relieve the severe physical symptoms of malignant small bowel obstruction (SBO) near the end of life. The objective of this study was to assess the impact of palliative decompressive gastrostomy tube on patient and caregiver well-being.

PATIENTS AND METHODS

We prospectively enrolled patients with a malignant SBO and their caregivers at the time of informed consent for decompressive gastrostomy tube placement. We collected the Edmonton Symptom Assessment Scale (ESAS) and the Functional Assessment of Chronic Illness Therapy-Palliative (FACIT-Pal-14) surveys from patients at baseline and at 2-week post-procedure follow-up. The Caregiver Burden Scale survey was administered to caregivers at baseline. Survey scores were compared using paired t-tests. We also conducted semistructured interviews with patients and their caregivers at two-week follow-up until thematic saturation was reached. Content analysis was used to identify themes with two independent coders.

RESULTS

We enrolled 15 patient-caregiver dyads. Preprocedure, the median caregiver burden scale score was 37.5 (significant burden ≥ 21). Eight patients (53%) survived to 2 weeks; among these patients, median ESAS scores (51 versus 43.5, p < 0.001) and median FACIT-Pal-14 scores (22 versus 32, p = 0.015) were significantly improved at 2-week follow-up. Interviews revealed three major themes: improved symptom management, new stressors, and opportunities for better education and resources.

CONCLUSIONS

Decompressive gastrostomy tubes effectively alleviated symptoms in patients with inoperable malignant SBOs. This palliative intervention may provide greater benefit if performed earlier, and caregivers and patients need improved resources and education for tube management to minimize added stressors.

Feasibility and acceptability of a nurse-led telehealth intervention (BOLSTER) to support patients with peritoneal carcinomatosis and their caregivers: A pilot randomized clinical trial

OBJECTIVE

Patients with advanced gynecologic (GYN) and gastrointestinal (GI) cancers frequently develop peritoneal carcinomatosis (PC), which limits prognosis and diminishes health-related quality of life (HRQoL). Palliative procedures may improve PC symptoms, yet patients and caregivers report feeling unprepared to manage ostomies, catheters, and other complex needs. Our objectives were to (1) assess the feasibility of an efficacy trial of a nurse-led telehealth intervention (BOLSTER) for patients with PC and their caregivers; and (2) assess BOLSTER's acceptability, potential to improve patients' HRQoL and self-efficacy, and potential impact on advance care planning (ACP).

METHODS

Pilot feasibility RCT. Recently hospitalized adults with advanced GYN and GI cancers, PC, and a new complex care need and their caregivers were randomized 1:1 to BOLSTER or enhanced discharge planning (EDP). We defined feasibility as a ≥ 50% approach-to-consent ratio and acceptability as ≥70% satisfaction with BOLSTER. We assessed patients' HRQoL and self-efficacy at baseline and six weeks, then compared the proportion experiencing meaningful improvements by arm. ACP documentation was identified using natural language processing.

RESULTS

We consented 77% of approached patients. In the BOLSTER arm, 91.0% of patients and 100.0% of caregivers were satisfied. Compared to EDP, more patients receiving BOLSTER experienced improvements in HRQoL (68.4% vs. 40.0%) and self-efficacy for managing symptoms (78.9% vs. 35.0%) and treatment (52.9% vs. 42.9%). The BOLSTER arm had more ACP documentation.

CONCLUSIONS

BOLSTER is a feasible and acceptable intervention with the potential to improve patients' HRQoL and promote ACP. An efficacy trial comparing BOLSTER to usual care is underway.

Improving the palliative-procedure decision-making process for patients with peritoneal carcinomatosis: A secondary analysis

BACKGROUND

Peritoneal carcinomatosis (PC) is common in patients with advanced gynecologic and gastrointestinal cancers. Frequently, patients with PC undergo palliative surgery or procedures to manage disease-related complications and side effects. However, there are limited data regarding patients' and family caregivers' decision-making processes about these procedures. Thus, we sought to describe the decision-making experiences of patients with PC who elect to pursue palliative surgical procedures and their family caregivers.

METHODS

We conducted a secondary analysis of qualitative data collected during a pilot randomized controlled trial of BOLSTER, a nurse-led telehealth intervention for patients with PC and their caregivers after an acute hospitalization and palliative procedure. Participants in both study arms described their experiences in semi-structured interviews. We re-analyzed coded qualitative data with a focus on understanding decision-making experiences surrounding palliative surgery and procedures using conventional content analysis.

RESULTS

Interviews from 32 participants, 23 patients and 9 caregivers, were analyzed. Participants reported their decision-making was complicated by illness uncertainty and a desire for clear, effective communication with surgical and medical oncology teams. Participants requested more information about the impact of palliative procedures on their daily life. Several also noted that, without improved understanding, a misalignment between patient and family caregiver goals and palliative procedures may inadvertently increase suffering.

CONCLUSION

Discussions related to patients' goals and preferences can improve the quality of treatment decision-making in patients with PC and their caregivers. Future research should test interventions to improve advanced cancer patients' illness understanding and decision-making surrounding palliative surgery and procedures.

The association of health-care contact days with physical function and survival in CCTG/AGITG CO.17

INTRODUCTION

Although contact days-days with health-care contact outside home-are increasingly adopted as a measure of time toxicity and treatment burden, they could also serve as a surrogate of treatment-related harm. We sought to assess the association between contact days and patient-reported outcomes and the prognostic ability of contact days.

METHODS

We conducted a secondary analysis of CO.17 that evaluated cetuximab vs supportive care in patients with advanced colorectal cancer. CO.17 collected European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 instrument data. We assessed the association between number of contact days in a window and changes in physical function and global health status and the association between number of contact days in the first 4 weeks with overall survival.

RESULTS

There was a negative association between the number of contact days and change in physical function (per each additional contact day: at 4 weeks, 1.50-point decrease; 8 weeks, 1.06-point decrease; P < .0001 for both) but not with global health status. This negative association was seen in patients receiving cetuximab but not supportive care. More contact days in the first 4 weeks was associated with worse overall survival for all participants and patients receiving cetuximab (per each additional contact day: all participants, adjusted hazard ratio [HR] = 1.07, 95% confidence interval [CI] = 1.05 to 1.10; and cetuximab, adjusted HR = 1.08, 95% CI = 1.05 to 1.11; P < .0001 for both).

CONCLUSIONS

In this secondary analysis of a clinical trial, more contact days early in the course were associated with declines in physical function and worse survival in all participants and in participants receiving cancer-directed treatment.

Palliative Surgery for Patients with Gastroesophageal Junction or Gastric Cancer: A Report on Clinical Observational Outcomes

BACKGROUND

Few studies have focused on palliative surgery in patients with advanced gastroesophageal junction (GEJ) or gastric cancer. We sought to evaluate clinical observational outcomes following palliative surgery in this population.

PATIENTS AND METHODS

Patients with GEJ or gastric cancer who underwent palliative surgery (1/2010-11/2022) were identified. The primary outcomes were symptom improvement, ability to tolerate an oral diet, discharge to home, 30 "good days" without hospitalization, and receipt of systemic treatment. Postoperative outcomes and survival were secondarily evaluated.

RESULTS

Among 93 patients, the median age was 59 (IQR 47-68) years, and the median Eastern Cooperative Oncology Group Performance Status (ECOG-PS) was 1 (range 0-3). The most frequent indication for palliative surgery was primary tumor obstruction [75 (81%) patients]. The most common procedures were feeding tube placement in 60 (65%) and intestinal bypass in 15 (16%) patients. A total of 75 (81%) patients experienced symptom improvement. Of these, 19 (25%) developed recurrent and 49 (65%) developed new symptoms. ECOG-PS was significantly associated with symptom-free time. Among those who underwent a bypass, resection, or ostomy creation for malignant obstruction, 16 (80%) tolerated an oral diet. Postoperatively, 87 (94%) were discharged home, 72 (77%) had 30 good days, and 64 (69%) received systemic treatment. Postoperative complications occurred in 35 (38%) patients, and 7 (8%) died within 30 days. The median survival time was 7.7 (95% CI 6.4-10.40) months.

CONCLUSIONS

Patients with incurable GEJ or gastric cancer can benefit from palliative surgery. Prognosis and performance status should inform goals-of-care discussions and patient selection for surgical palliation.

Perioperative/postoperative anxiety and its interventions in gynecological cancers: a comprehensive review of clinical evidence

Gynecological cancers are prevalent malignancies among females, and surgical intervention is the primary therapeutic approach offering the possibility of a definitive cure. Recent research has highlighted the susceptibility of gynecological cancer patients to experiencing anxiety symptoms during the perioperative and postoperative phases, with this psychological condition being linked to suboptimal recovery following surgery. Nevertheless, certain interventions have shown promise in mitigating perioperative and postoperative anxiety in gynecological cancer patients. In this study, we conducted a comprehensive review to collect the existing evidence on this subject. Through a systematic search across six common databases, we screened and included 28 pertinent studies. The current review emphasizes the elevated occurrence of perioperative and postoperative anxiety among patients with gynecological cancers (i.e., uterine, cervical, ovarian, endometrial, and vulval cancers). Specific nursing interventions (i.e., crisis intervention nursing, multidisciplinary collaborative continuous nursing, psychological nursing, comprehensive psychological nursing, reminiscence therapy involved care, cognitive behavioral stress management, hospital-family integrated continuation nursing, high-quality nursing care, relaxation-focused nursing program, and relaxation/counseling intervention) and psychotropic medications may serve as dependable approaches to mitigate perioperative and postoperative anxiety. This study represents a novel contribution to the literature by providing a characterization of perioperative and postoperative anxiety in the context of gynecological oncology. The findings underscore the significance of addressing perioperative and postoperative anxiety as a critical clinical concern for individuals with gynecological cancers, emphasizing the need for further research to develop effective interventions.

Use and Outcomes of Dexamethasone in the Management of Malignant Small Bowel Obstruction

Objective

To describe rates of dexamethasone use in the nonoperative management of malignant small bowel obstruction (mSBO) and their outcomes.

Background

mSBO is common in patients with advanced abdominal-pelvic cancers. Management includes prioritizing quality of life and avoiding surgical intervention when possible. The use of dexamethasone to restore bowel function is recommended in the National Comprehensive Cancer Network guidelines for mSBO. Yet, it is unknown how often dexamethasone is used for mSBO and whether results from nonresearch settings support its use.

Methods

This is a multicenter retrospective cohort study including unique admissions for mSBO from January 1, 2019 to December 31, 2021. Dexamethasone use and management outcomes were summarized with descriptive statistics and multiple logistic regression.

Results

Among 571 admissions (68% female, mean age 63 years, 85% history of abdominal surgery) that were eligible and initially nonoperative, 26% [95% confidence interval (CI) = 23%-30%] received dexamethasone treatment (69% female, mean age 62 years, 87% history of abdominal surgery). Dexamethasone use by site ranged from 13% to 52%. Among dexamethasone recipients, 13% (95% CI = 9%-20%) subsequently required nonelective surgery during the same admission and 4 dexamethasone-related safety-events were reported. Amongst 421 eligible admissions where dexamethasone was not used, 17% (95% CI = 14%-21%) required nonelective surgery. Overall, the unadjusted odds ratio (OR) for nonelective surgery with dexamethasone use compared to without its use was 0.7 (95% CI = 0.4-1.3). Using multiple logistic regression, OR after adjusting for site, age, sex, history of abdominal surgery, nasogastric tube, and Gastrografin use was 0.6 (95% CI = 0.3-1.1).

Conclusion

Dexamethasone was used in about 1 in 4 eligible mSBO admissions with high variability of use between tertiary academic centers. This multicenter retrospective cohort study suggested an association between dexamethasone use and lower rates of nonelective surgery, representing a potential opportunity for quality improvement.

Reporting time toxicity in prospective cancer clinical trials: A scoping review

PURPOSE

This review aimed to assess the measurement and reporting of time toxicity (i.e., time spent receiving care) within prospective oncologic studies.

METHODS

On July 23, 2023, PubMed, Scopus, and Embase were queried for prospective or randomized controlled trials (RCT) from 1984 to 2023 that reported time toxicity as a primary or secondary outcome for oncologic treatments or interventions. Secondary analyses of RCTs were included if they reported time toxicity. The included studies were then evaluated for how they reported and defined time toxicity.

RESULTS

The initial query identified 883 records, with 10 studies (3 RCTs, 2 prospective cohort studies, and 5 secondary analyses of RCTs) meeting the final inclusion criteria. Treatment interventions included surgery (n = 5), systemic therapies (n = 4), and specialized palliative care (n = 1). The metric "days alive and out of the hospital" was used by 80% (n = 4) of the surgical studies. Three of the surgical studies did not include time spent receiving ambulatory care within the calculation of time toxicity. "Time spent at home" was assessed by three studies (30%), each using different definitions. The five secondary analyses from RCTs used more comprehensive metrics that included time spent receiving both inpatient and ambulatory care.

CONCLUSIONS

Time toxicity is infrequently reported within oncologic clinical trials, with no standardized definition, metric, or methodology. Further research is needed to identify best practices in the measurement and reporting of time toxicity to develop strategies that can be implemented to reduce its burden on patients seeking cancer care.

Palliative surgery: state of the science and future directions

Palliative surgical procedures are operations that aim to alleviate symptoms in a patient with serious, life-limiting illness. They are common, particularly within the field of surgical oncology. However, few high-quality studies have attempted to measure the durability of improvements in symptoms and quality of life after palliative surgery. Furthermore, many of the studies that do exist are outdated and employ highly inconsistent definitions of palliative surgery. Consequently, the paucity of robust and reliable evidence on the benefits, risks, and trade-offs of palliative surgery hampers clinical decision-making for patients and their surgeons. The evidence for palliative surgery suggests that, with effective communication about goals of care and careful patient selection, palliative surgery can provide symptomatic relief and reduce healthcare burdens for certain seriously ill patients.

Experiences of patients with peritoneal carcinomatosis-related complex care needs and their caregivers

BACKGROUND

Patients with peritoneal carcinomatosis (PC) frequently undergo palliative procedures, yet these patients and their caregivers report being unprepared to manage ostomies, drains, and other complex care needs at home. The purpose of this study was to characterize the unique needs of these patients and their caregivers during care transitions.

METHODS

Patients completed measures of health status and advance care planning, caregivers completed measures of preparedness and burden, and all participants completed measures of depression and anxiety. Participants detailed their experiences in individual, semi-structured interviews. We analyzed data using descriptive statistics and conventional content analysis.

RESULTS

Sixty-one patients and 39 caregivers completed baseline measures. Twenty-four (39.3%) patients acknowledged their terminal illness and seven (11.5%) had discussed end-of-life care preferences with clinicians. Most (26/39, 66.7%) caregivers provided daily care. Among caregivers who managed symptoms, few were taught how to do so (6/20, 30%). Seven patients (11.5%) and seven caregivers (17.9%) met case criteria for anxiety, while 15 patients (24.6%) and two caregivers (5.1%) met case criteria for depression. Interview participants described a diagnosis of PC as a turning point for which there is no road map and identified the need for health systems change to minimize suffering.

CONCLUSION

Patients with PC and their caregivers are highly burdened by symptoms and care needs. Patients' prognostic understanding and advance care planning are suboptimal. Interventions that train patients with PC and their caregivers to perform clinical care tasks, facilitate serious illness conversations, and provide psychosocial support are needed.

A Comprehensive Review on Managing Fracture Calcaneum by Surgical and Non-surgical Modalities

This comprehensive review delves into the multifaceted landscape of calcaneal fractures, thoroughly examining their aetiology, clinical presentation, and diverse management strategies. Encompassing surgical and non-surgical approaches, the review scrutinises critical aspects such as patient compliance, rehabilitation protocols, and long-term follow-up considerations. Surgical modalities, propelled by recent innovations like minimally invasive techniques and advanced fixation materials, are juxtaposed with non-surgical interventions, emphasising the pivotal role of patient education and adherence to optimise outcomes. The synthesis of critical findings underscores the need for individualised care and multidisciplinary collaboration in clinical practice. Moreover, the review outlines recommendations for healthcare practitioners and identifies promising areas for future research, including biomechanical studies and telerehabilitation. This comprehensive exploration aims to contribute to the ongoing evolution of calcaneal fracture management, ultimately enhancing patient care and outcomes in this complex orthopaedic realm.

Malignant Bowel Obstruction: A Retrospective Multicenter Cohort Study

BACKGROUND

Malignant bowel obstruction (MBO) is a serious clinical entity that requires surgical intervention in almost 50% of cases. However, overall survival remains low even for operable cases. The aim of the present study was to investigate the correlation between patients' characteristics, perioperative details, histopathological results and postoperative outcomes of patients who were operated on due to MBO.

METHODS

A retrospective search of patients who were operated on due to MBO in a university and a rural hospital was conducted. Patients' characteristics, perioperative details, histopathological results and postoperative outcomes were reported. Univariable and multivariable analysis was performed.

RESULTS

Seventy patients were included with a mean age of 76.1 ± 10.6 years. The 30-day mortality rate was 18.6%, the Intensive Care Unit (ICU) admission rate was 17.1% and the mean length of stay (LOS) was 12.4 ± 5.7 days. Postoperative 30-day mortality was associated with increased age, known malignant recurrence, microscopically visible metastatic foci and defunctioning stoma creation. Colorectal malignancy type, sigmoid obstruction and primary anastomosis were correlated with decreased 30-day mortality. In addition, operation at the university hospital led to increased LOS, while stoma creation led to decreased LOS. Finally, ICU admission rates were increased for operations at university hospitals, at least one comorbidity, known malignant recurrence and longer preoperative waiting interval, whereas they were decreased for colorectal primary malignancy type.

CONCLUSIONS

Surgery due to MBO leads to increased morbidity and mortality. Therefore, prospective studies are needed to highlight inter-patient differences regarding the best individualized therapeutic strategy.

Telemedicine and Cancer Clinical Research: Opportunities for Transformation

ABSTRACT

Telemedicine represents an established mode of patient care delivery that has and will continue to transform cancer clinical research. Through telemedicine, opportunities exist to improve patient care, enhance access to novel therapies, streamline data collection and monitoring, support communication, and increase trial efficiency. Potential challenges include disparities in technology access and literacy, physical examination performance, biospecimen collection, privacy and security concerns, coverage of services by insurance, and regulatory considerations. Coupled with artificial intelligence, telemedicine may offer ways to reach geographically dispersed candidates for narrowly focused cancer clinical trials, such as those targeting rare genomic subsets. Collaboration among clinical trial staff, clinicians, regulators, professional societies, patients, and their advocates is critical to optimize the benefits of telemedicine for clinical cancer research.
