Clinical outcomes of curative surgical resection of peritoneal metastasis in patients with colorectal cancer: A long-term follow-up study.

ABSTRACT:

Introduction

Colorectal cancer with peritoneal metastasis (PM) has been considered a non-curative disease. PM is associated with reduced overall survival (OS) and worse prognosis compared with metastasis at other sites. We aimed to investigate the treatment outcome and recurrence after curative resection of colorectal PM during a long-term follow-up.

Methods

Patients who were diagnosed with colorectal PM and underwent surgery between December 2001 and December 2019 were included (n = 309). Curative resection was defined as PM resection without residual disease after surgery (complete macroscopic resection).

Results

Of 309 patients, 208 (67.8%) had PM as an initially metastatic disease. Curative (R0/1) resection was achieved in 155 (50.2%) patients, while non-curative operation (R2 resection or palliative operation including colostomy) was performed in 154 (49.8%) patients. Compared with patients who underwent non-curative operation, those with curative resection more often had a single PM on preoperative imaging (34.2% vs. 20.8%, p = 0.011) and postoperative results (59.4% vs. 22.7%, p < 0.001) and less often had concurrent metastasis (distant lymph node, liver, or lung) at the time of surgery (p < 0.001). During a median follow-up of 90.4 months, 80.6% (125/155) patients had recurrence in the curative resection group; the peritoneum was the most common site (56.0%). The median OS was 47.7 months (95% CI, 39.2-56.2) in the curative resection group and 24.8 months (95% CI, 20.8-28.9) in the non-curative resection group, respectively (p < 0.001). In particular, twenty-six patients without recurrence showed long-term survival after curative resection (median OS, 87.1 months; range, 40.1-127.5).

Conclusion

Surgical resection can be considered for selected patients with colorectal PM because a significant number of them could seize the cure changes during their treatment continuum.

Project description:BackgroundMost recurrences of non-small cell lung cancer (NSCLC) after lung resection occur within 5 years, which is why 5-year overall survival rates are used to give prognoses for lung cancer. Elderly individuals also often show comorbidities and may die from other diseases. Few studies have examined the long-term prognosis of elderly patients with NSCLC, and no reports have investigated drop-out from follow-up after resection of NSCLC, including in elderly patients. This retrospective cohort study analyzed and surveyed long-term prognosis and drop-out from follow-up, including in elderly patients, after resection of lung cancer.MethodsWe identified 349 consecutive patients after lung resection between January 2009 and March 2011. Twenty-two cases were excluded because of small cell lung cancer, past metachronous multiple lung cancers, recurrences of lung cancer, surgical biopsy, and other reasons. We investigated recurrences and causes of death in all patients and defined cases for which follow-up could not be conducted even by telephone or documentation from patients or the public office as cases of drop-out from follow-up.ResultsOf the 327 cases analyzed, 81 cases dropped out from follow-up and 246 cases completed >10 years of follow-up. Multivariable analysis demonstrated age ≥75 years [odds ratio 1.83; 95% confidence interval (CI): 1.01-3.32] and female sex (odds ratio 1.87, 95% CI: 1.06-3.3) as independent risk factors for drop-out from follow-up. Recurrence was detected >5 years after surgery in 5 cases (2.0%, 5/246 cases). Five- and 10-year overall survival rates were 67.2% and 52.9% for patients <75 years of age, and 42.1% and 21.1% for patients of age ≥75 years (P<0.001). Overall survival was significantly better for those of age <75 years than for those of age ≥75 years. Disease-specific survival did not differ significantly between groups (5-year disease-specific survival rate: 71.9% vs. 73.4%; 10-year disease-specific survival: 66.0% vs. 61.2%, P=0.80). Using Cox proportional hazard regression, age ≥75 years (hazard ratio 2.221; 95% CI: 1.507-3.274; P<0.001) and stage ≥2 (hazard ratio 2.628; 95% CI: 1.868-3.698; P<0.001) were significantly associated with overall survival.ConclusionsIn patients with NSCLC after lung resection, age ≥75 years and female sex were risk factors for dropping out from follow-up over 10 years. In addition, patients ≥75 years of age have a high possibility of dying from other diseases and sufficient consideration of and informed consent for surgical indications are necessary.

Project description:BackgroundColorectal cancer (CRC) is among the most frequently diagnosed cancers. Approximately 20-30% of stage I-III CRC patients develop a recurrent tumour or metastases after curative surgical resection. Post-operative follow-up is indicated for the first five years after curative surgical resection. As intensified follow-up after curative surgical resection has shown no effect on survival, patient organisations and policy makers have advocated for a more patient-centred approach to follow-up. The objective of this study is to successfully implement patient-led, home-based follow-up (PHFU) in six hospitals in The Netherlands, with as ultimate aim to come to a recommendation for a patient-centred follow-up schedule for stage I-III CRC patients treated with surgical resection with curative intent.MethodsThis study is designed as a stepped-wedge cluster-randomised trial (SW-CRT) in six participating centres. During the trial, three centres will implement PHFU after six months; the other three centres will implement PHFU after 12 months of inclusion in the control group. Eligible patients are those with pT2-4N0M0 or pT1-4N1-2M0 CRC, who are 18 years or older and have been free of disease for 12 months after curative surgical resection. The studied intervention is PHFU, starting 12 months after curative resection. The in-hospital, standard-of-care follow-up currently implemented in the participating centres functions as the comparator. The proportion of patients who had contact with the hospital regarding CRC follow-up between 12-24 months after curative surgical resection is the primary endpoint of this study. Quality of life, fear of cancer recurrence, patient satisfaction, cost-effectiveness and survival are the secondary endpoints.DiscussionThe results of this study will provide evidence on whether nationwide implementation of PHFU for CRC in The Netherlands will be successful in reducing contact between patient and health care provider. Comparison of PROMs between in-hospital follow-up and PHFU will be provided. Moreover, the cost-effectiveness of PHFU will be assessed.Trial registrationDutch Trail Register (NTR): NL9266 (Registered on January 1st, 2021).
