Does the primary tumour location affect the prognosis of patients with colorectal cancer peritoneal metastases treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy?

Abstract Background The impact of primary tumour location on the prognosis of patients with peritoneal metastasis (PM) arising from colorectal cancer (CRC) after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is rarely discussed, and the evidence is still limited. Methods Patients with PM arising from CRC treated with CRS and HIPEC at the China National Cancer Center and Huanxing Cancer Hospital between June 2017 and June 2019 were systematically reviewed. Clinical characteristics, pathological features, perioperative parameters, and prognostic data were collected and analysed. Results A total of 70 patients were divided into two groups according to either colonic or rectal origin (18 patients in the rectum group and 52 patients in the colon group). Patients with PM of a colonic origin were more likely to develop grade 3–4 postoperative complications after CRS+HIPEC (38.9% vs 19.2%, P = 0.094), but this difference was not statistically significant. Patients with colon cancer had a longer median overall survival (OS) than patients with rectal cancer (27.0 vs 15.0 months, P = 0.011). In the multivariate analysis, the independent prognostic factors of reduced OS were a rectal origin (HR 2.15, 95% CI 1.15–4.93, P = 0.035) and incomplete cytoreduction (HR 1.99, 95% CI 1.06–4.17, P = 0.047). Conclusion CRS is a complex and potentially life-threatening procedure, and we suggest that the indications for CRS+HIPEC in patients with PM of rectal origin be more restrictive and that clinicians approach these cases with caution.

The Impact

Abstract Background This study aimed to evaluate the impact of postoperative complications on long-term survival in patients with peritoneal metastasis (PM) arising from colorectal cancer (CRC) treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Methods Patients with PM arising from CRC treated with CRS and HIPEC were systematically reviewed at the China National Cancer Center and Huanxing Cancer Hospital from June 2017 to June 2019. High-grade complications that occurred within 30 days were defined as grade 3 to 4 events according to the Common Terminology Criteria for Adverse Events (CTCAE) classification. Univariate and multivariable Cox regression models for overall survival were created. Predictors of high-grade postoperative complications were evaluated with univariate and multivariate logistic regression analyses. Results In all, 86 consecutive cases were included in this study. Forty-one patients (47.7%) developed postoperative complications, while 22 patients (25.6%) experienced high-grade complications. No mortality occurred during the postoperative period. The median survival of all patients was 25 months, and the estimated 3-year overall survival (OS) rate was 35.0%. In the multivariable Cox regression analysis, a high peritoneal carcinomatosis index (PCI) score (HR, 1.07, 95% CI, 1.01–1.14; P=0.015) and grade 3–4 postoperative complications (HR, 1.86, 95% CI, 1.22–3.51; P=0.044) correlated with worse overall survival. High estimated blood loss (OR, 1.01, 95% CI, 1.01–1.02; P< 0.001) was identified as an independent risk factor for developing high-grade complications. Conclusion Careful patient selection, high levels of technical skill and improved perioperative management are crucial to ensure patient survival benefits after CRS+HIPEC.

Abstract Background Chemosensitivity testing, including collagen gel droplet-embedded culture drug sensitivity test, has proven to be a useful tool in therapeutic decision-making. This retrospective analysis investigated chemosensitivity testing of peritoneal metastases collected during cytoreductive surgery (CRS), and its impact on survival in patients with colorectal cancer. Methods All patients with peritoneal metastasis from colorectal cancer who underwent CRS with or without hyperthermic intraperitoneal chemotherapy (HIPEC) between November 2008 and October 2014 were included. The growth inhibition rate was expressed as the ratio between the image density after treatment (T) and that before treatment (control, C). Tumours with a reduction in T/C ratio of less than 20 per cent were defined as resistant and those with a reduction of 20 per cent or more as sensitive. Groups were compared for overall (OS) and disease-free (DFS) survival. Results Of 84 eligible patients, 81 received neoadjuvant chemotherapy (NACT), including 56 patients with an oxaliplatin-based regimen. Mean(s.d.) follow-up was 23·4(22·9) months. The median overall survival of all patients was 19·0 (i.q.r. 5·7–36·1) months, with a progression-free survival time of 10·1 (4·5–17·0) months. Patients who received oxaliplatin-based NACT had significantly altered chemosensitivity to oxaliplatin; only 20 of 51 such patients showed chemosensitivity to oxaliplatin compared with 16 of 24 who did not undergo oxaliplatin-based NACT (P = 0·046). However, patients who showed chemoresistance to oxaliplatin had similar OS to those with chemosensitivity (18·8 versus 18·1 months; P = 0·835). The choice of HIPEC agents in patients who received oxaliplatin-based NACT did not significantly influence survival (oxaliplatin versus mitomycin C: median OS 20·6 (10·9–24·8) versus 19·0 (10·5–34·6) months, P = 0·811; DFS 6·6 (2·8–25·7) versus 9·3 (4·1–13·9) months, P = 0·191). Conclusion Patients who had oxaliplatin-based NACT showed a higher rate of chemoresistance to oxaliplatin at the time of CRS and HIPEC. The impact of chemosensitivity testing on OS remains unclear and needs further investigation.

Peritoneal Cancer

AbstractPeritoneal metastasis from colorectal cancer (PM-CRC) is used to be considered a systemic and fatal condition; however, it has been growingly accepted that PM-CRC can still be local disease rather than systemic disease as analogous to liver or lung metastasis.Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is now considered an optimal treatment for PM-CRC with accumulating evidence. There is a good reason that CRS + HIPEC, widely accepted as a standard of care for pseudomyxoma peritonei (PMP), could be a viable option for PM-CRC given a similarity between PM-CRC and PMP.Recent years have also seen that modern systemic chemotherapy with or without molecular targeted agents can be effective for PM-CRC. It is possible that neoadjuvant or adjuvant chemotherapy combined with CRS + HIPEC could further improve outcomes.Patient selection, utilizing modern images and increasingly laparoscopy, is crucial. Particularly, diagnostic laparoscopy is likely to play a significant role in predicting the likelihood of achieving complete cytoreduction and assessing the peritoneal cancer index score.
