Abstract
Background: Adjuvant chemotherapy (AC) for colorectal cancer (CRC) has led to substantial improvement in survival. Several clinical trials advocate the initiation of AC within 6-8 weeks of surgical resection based on evidence of improved survival with early initiation of AC. We aim to evaluate factors that predict initiation and completion of AC, subsequently improving survival. Methods: We identified 451 patients who underwent resection for CRC between 2014 and 2022. One hundred ten patients had stage II/III colorectal cancer who underwent resection followed by AC. Multivariable logistic regression analysis was performed to identify factors significantly predicting delay in AC >8 weeks. Secondary outcomes included chemotherapy completion rate, recurrence-free survival, and overall survival. Results: The final analysis included 110 patients. The median time to initiation of adjuvant chemotherapy (TIAC) was 6.9 weeks (IQR: 5.8-9.5). In total, 36.4% of patients had a delay >8 weeks to initiation of AC, and only 40% completed treatment. The surgical approach (open vs laparoscopic vs robotic) had no effect on the TIAC. On multivariable logistic regression analysis, preoperative albumin ≥3.5 (OR = .31; 95% CI: .12-.80) was an independent predictor of timely initiation of AC. Completion of AC was associated with a higher overall survival. Discussion: Preoperative nutritional status predicted delay in initiation of AC. Patients with a delay in AC beyond eight weeks had a lower rate of AC completions and worse survival. It is imperative to optimize this aspect of treatment as it correlates with survival.

Association between social determinants of health and delayed postoperative adjuvant therapy among patients undergoing resection of pancreatic cancer. J Surg Oncol 2024; 129:850-859. [PMID: 38151795 DOI: 10.1002/jso.27571] [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: 12/01/2023] [Accepted: 12/07/2023] [Indexed: 12/29/2023]
Abstract
BACKGROUND AND OBJECTIVES Pancreatic cancer (PDAC) requires a multimodality approach. We sought to define the association between social determinants of health (SDOH) and delayed or nonreceipt of adjuvant chemotherapy (aCT) among patients undergoing PDAC resection. METHODS Data on patients who underwent PDAC resection between 2014 and 2020 were identified from Medicare Standard Analytic Files and merged with the county-level social vulnerability index (SVI). Mediation analysis defined the association between SVI subthemes and aCT receipt. RESULTS Among 24 078 patients, 47.7% received timely aCT, 17.7% received delayed aCT, and 34.6% did not receive any aCT. High SVI was associated with delay (odds ratio [OR] 1.22, 95% confidence interval [CI] 1.10-1.34) and nonreceipt of aCT (OR 1.30, 95% CI 1.20-1.41) (both p < 0.05). 73.1% of the variation in timely aCT receipt was directly attributable to SVI, whereas 26.9% of the effect was due to indirect mediators including hospital volume (6.4%), length-of-stay (7.9%) and postoperative complications (12.6%). Socioeconomic status (delayed aCT: OR 1.25, 95% CI 1.13-1.38; nonreceipt aCT: OR 1.25, 95% CI 1.15-1.36) and household composition and disability (delayed aCT: OR 1.30, 95% CI 1.17-1.43; nonreceipt aCT: OR 1.19, 95% CI 1.09-1.29) were associated with receipt of aCT (both p < 0.001). CONCLUSIONS Most of the disparities in receipt of aCT after PDAC surgery are driven by underlying SDOH such as SVI.

Sun BJ, Daniel SK, Lee B. The Role of Prophylactic and Adjuvant Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in Prevention of Peritoneal Metastases in Advanced Colorectal Cancer. J Clin Med 2023; 12:6443. [PMID: 37892582 PMCID: PMC10607874 DOI: 10.3390/jcm12206443] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 09/28/2023] [Accepted: 10/08/2023] [Indexed: 10/29/2023] Open
Abstract
Hyperthermic intraperitoneal chemotherapy (HIPEC) is a locoregional therapy that may be combined with cytoreductive surgery (CRS) to treat patients with colorectal cancer and peritoneal metastases (PM). In recent years, three randomized controlled trials (RCTs) have investigated the role of prophylactic or adjuvant HIPEC in preventing the development of PM in patients with high-risk colorectal cancer: PROPHYLOCHIP and COLOPEC evaluated adjuvant HIPEC, and HIPECT4 studied concurrent HIPEC and CRS. Although PROPHYLOCHIP and COLOPEC were negative trials, a great deal may be learned from their methodology, outcome measures, and patient selection criteria. HIPECT4 is the first RCT to show a clinical benefit of HIPEC in high-risk T4 colorectal cancer, demonstrating improved locoregional disease control with the addition of HIPEC to CRS with no increase in the rate of complications. This review critically examines the strengths and limitations of each major trial and discusses their potential impact on the practice of HIPEC. Several additional ongoing clinical trials also seek to investigate the role of HIPEC in preventing PM in advanced colorectal cancer.

Abstract
Background Patients with ulcerative colitis are reported to be at increased risk of colorectal cancer and are also at high risk of postoperative complications. However, the incidence of postoperative complications in these patients and how the type of surgery performed affects prognosis are not well understood. Methods Data collected by the Japanese Society for Cancer of the Colon and Rectum on ulcerative colitis patients with colorectal cancer between January 1983 and December 2020 were analyzed according to whether total colorectal resection was performed with ileoanal anastomosis (IAA), ileoanal canal anastomosis (IACA), or permanent stoma creation. The incidence of postoperative complications and the prognosis for each surgical technique were investigated. Results The incidence of overall complications was not significantly different among the IAA, IACA, and stoma groups (32.7%, 32.3%, and 37.7%, respectively; p = 0.510). The incidence of infectious complications was significantly higher in the stoma group (21.2%) than in the IAA (12.9%) and IACA (14.6%) groups (p = 0.048); however, the noninfectious complication rate was lower in the stoma group (13.7%) than in the IAA (21.1%) and IACA (16.2%) groups (p = 0.088). Five-year relapse-free survival was higher in patients without complications than in those with complications in the IACA group (92.8% vs. 75.2%; p = 0.041) and the stoma group (78.1% vs. 71.2%, p = 0.333) but not in the IAA group (90.3% vs. 90.0%, p = 0.888). Conclusion The risks of infectious and noninfectious complications differed according to the type of surgical technique used. Postoperative complications worsened prognosis.

Relationship between the timing of chemotherapy and surgical complications following surgical biopsy in children with malignant solid tumors. Pediatr Blood Cancer 2023; 70:e30030. [PMID: 36184783 DOI: 10.1002/pbc.30030] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 08/07/2022] [Accepted: 09/04/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND Biopsies for diagnosis before chemotherapy is common in children with malignant solid tumors. Wound healing is delayed by chemotherapy; however, the ideal interval between biopsy and chemotherapy remains unknown. We aimed to summarize the relationship between chemotherapy timing and postoperative surgical complications. PROCEDURE We retrospectively reviewed patients with malignant solid tumors who underwent chemotherapy after surgical biopsy at our institution between January 2014 and August 2020. The primary outcomes were postoperative surgical complications (within 30 days) and the timing of chemotherapy. RESULTS Forty-three patients were analyzed. The types of tumors were neuroblastoma (n = 20), hepatoblastoma (n = 10), Ewing sarcoma (n = 5), germ cell tumor (n = 3), angiosarcoma (n = 1), clear cell sarcoma (n = 1), ganglioneuroblastoma (n = 1), rhabdoid tumor (n = 1), and rhabdomyosarcoma (n = 1). The operative procedures were thoracoscopy (n = 5), laparotomy (n = 17), laparoscopy (n = 14), and superficial (n = 7). The median time [range] to chemotherapy after biopsy was 4 [0-21] days. No surgical complications occurred before chemotherapy, and two (4.7%) patients experienced complications after chemotherapy. These included postoperative hemorrhage (grade 3) and surgical site infection (grade 1). Chemotherapy was initiated 1 and 6 days after biopsy, respectively, in these cases. Complications occurred 10 and 23 days after biopsy, respectively. CONCLUSION The rate of postoperative surgical complications related to biopsy seems acceptable, even when chemotherapy was initiated in the early postoperative period. Early initiation of chemotherapy after biopsy may be a suitable option, particularly in children with bulky or symptomatic malignant solid tumors.
