A re-look at the modified Ryan regression scoring system in esophageal cancer-validation of prognostic significance and comparison with other less commonly used systems.

BACKGROUND: Neoadjuvant chemoradiotherapy (NACRT) using CROSS protocol is currently the treatment of choice for esophageal cancer (EC). Tumor response grade (TRG) is a mandatory reporting criterion in most guidelines. One of the most commonly used TRG systems is the modified Ryan system. We aim to assess the TRG using modified Ryan and seven other systems (Mandard, Chireac, Swisher, Japanese esophageal society guidelines, modified rectal cancer regression grading (mRCRG), CROSS, and Becker) to evaluate their reproducibility and role as a prognostic marker. MATERIALS AND METHODS: Two pathologists independently reviewed all cases of post-NACRT (CROSS) EC, to score TRGs and other histological parameters. Inter-rater agreement assessment for different TRG systems and correlation with disease-free survival (DFS) was performed. RESULTS: Our series includes 93 patients with predominantly mid-esophageal squamous cell carcinoma. Complete pathological response (pCR) was noted in 47% (44/93) patients. The kappa inter-rater agreement score for the Ryan system was substantial (0.774), while it was almost perfect agreement for tumor percentage assessment-based systems (Swisher, CROSS, and Becker). Only the mRCRG TRGs correlated significantly with prognosis, while the Ryan system did not. Tumor stage and pCR status did not correlate with DFS, though the nodal stage was clinically significant. CONCLUSION: Though the inter-rater concordance was optimal for all the TRG systems studied, only the mRCRG system showed prognostic significance, while the commonly used modified Ryan system did not. It may be worthwhile to look at further evaluating other systems like mRCRG for inclusion in minimum dataset reporting.

Impact of Covid-19 on gastrointestinal cancer surgery: A National Survey.

PURPOSE: To understand the actual impact of the Covid-19 pandemic and frame the future strategies, we conducted a pan India survey to study the impact on the surgical management of gastrointestinal cancers. METHODS: A national multicentre survey in the form of a questionnaire from 16 tertiary care gastrointestinal oncology centres across India was conducted from January 2019 to June 2021 that was divided into a 15-month pre-Covid era and a similar period of active Covid pandemic era. RESULTS: There was significant disruption of services; 13 (81%) centres worked as dedicated Covid care centres and 43% reported suspension of essential care for more than 6 months. In active Covid phase, there was a 14.5% decrease in registrations and proportion of decrease was highest in the centres from South zone (22%). There was decrease in resections across all organ systems; maximum reduction was noted in hepatic resections (33%) followed by oesophageal and gastric resections (31 and 25% respectively). There was minimal decrease in colorectal resections (5%). A total of 584 (7.1%) patients had either active Covid-19 infection or developed infection in the post-operative period or had recovered from Covid-19 infection. Only 3 (18%) centres reported higher morbidity, while the rest of the centres reported similar or lower morbidity rates when compared to pre-Covid phase; however, 6 (37%) centres reported slightly higher mortality in the active Covid phase. CONCLUSION: Covid-19 pandemic resulted in significant reduction in new cancer registrations and elective gastrointestinal cancer surgeries. Perioperative morbidity remained similar despite 7.1% perioperative Covid 19 exposure.

Can the CROSS protocol be safely implemented in real world scenario with broader eligibility criteria? Experience from a tertiary care centre in India.

BACKGROUND: The Chemoradiotherapy for Oesophageal Cancer Followed by Surgery Study (CROSS) trial established a new benchmark in the management of oesophageal cancer with neoadjuvant chemoradiation followed by surgery with a marked benefit for squamous cell carcinomas (SCCs). We evaluate if the CROSS protocol can be safely implemented with a broader eligibility criteria in a real-world setting. METHODS: A retrospective analysis of 80 patients of SCC oesophagus was performed, who were treated with neoadjuvant chemoradiation with radiation therapy (RT) to 41.4 Gy/23 Fr/4.5 weeks and weekly paclitaxel and carboplatin, followed by surgery at our institute between 2012 and 2019. Eligibility for the use of this regimen was expanded beyond the limits of size and stage allowed in the CROSS trial. RESULTS: The median age of this cohort was 57 years (range: 39-78 years). Most of the patients (77/80; 96.3%) had T3 disease and 25% patients (20/80) had N2/N3 disease. Thirty-three patients (41.3%) had the disease beyond CROSS eligibility criteria. All patients completed planned course of RT and five cycles of weekly chemotherapy were received by 61 patients (76.2%). Overall pathological complete response (pCR) could be achieved in 33 patients (41.3%). Among 33 CROSS ineligible patients, 14 (42.4%) had pCR. Acute grade 3 dysphagia and grade ≥ 3 neutropenia were seen in seven cases (8.3%) and nine cases (10.7%), respectively. At a median follow-up of 16 months, 1-year and 2-year overall survival (OS) were 84.4% (95% confidence interval (CI): 73.5%-91.1%) and 76.3% (95% CI: 63.2%-85.2%), respectively, for the entire cohort. For CROSS ineligible patients, 1-year and 2-year OS were 82% (95% CI: 61.8%-92.2%) and 72.7% (95% CI: 50.4%-86.2%), respectively. On univariate analysis, patients who had pathologically N0 disease had significantly better 2-year OS (85.7% versus 48.4%; p = 0.03) as compared to pathologically N+ patients. On univariate and multivariate analysis, there was no significant difference in OS and progression free survival between CROSS eligible and CROSS ineligible patients. CONCLUSION: CROSS protocol can be safely implemented for carefully selected patients of SCC oesophagus outside clinical trial settings with expanded eligibility criteria.

Enhanced recovery after surgery (ERAS) in cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC): a cross-sectional survey.

OBJECTIVES: Enhanced recovery after surgery (ERAS) protocols have been questioned in patients undergoing cytoreductive surgery (CRS) with/without hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal malignancies. This survey was performed to study clinicians' practice about ERAS in patients undergoing CRS-HIPEC. METHODS: An online survey, comprising 76 questions on elements of prehabilitation (n=11), preoperative (n=8), intraoperative (n=16) and postoperative (n=32) management, was conducted. The respondents included surgeons, anesthesiologists, and critical care specialists. RESULTS: The response rate was 66% (136/206 clinicians contacted). Ninety-one percent of respondents reported implementing ERAS practices. There was encouraging adherence to implement the prehabilitation (76-95%), preoperative (50-94%), and intraoperative (55-90%) ERAS practices. Mechanical bowel preparation was being used by 84.5%. Intra-abdominal drains usage was 94.7%, intercostal drains by 77.9% respondents. Nasogastric drainage was used by 84% of practitioners. The average hospital stay was 10 days as reported by 50% of respondents. A working protocol and ERAS checklist have been designed, based on the results of our study, following recent ERAS-CRS-HIPEC guidelines. This protocol will be prospectively validated. CONCLUSIONS: Most respondents were implementing ERAS practices for patients undergoing CRS-HIPEC, though as an extrapolation of colorectal and gynecological guidelines. The adoption of postoperative practices was relatively low compared to other perioperative practices.

Radical radiotherapy or chemoradiotherapy for inoperable, locally advanced, non-small cell lung cancer: Analysis of patient profile, treatment approaches, and outcomes for 213 patients at a tertiary cancer center.

INTRODUCTION: Radical radiotherapy (RT) with curative intent, with or without chemotherapy, is the standard treatment for inoperable, locally advanced nonsmall cell lung cancer (NSCLC). MATERIALS AND METHODS: We retrospectively reviewed the data for all 288 patients who presented with inoperable, locally advanced NSCLC at our institution, between May 2011 and December 2016. RESULTS: RT alone or sequential chemoradiotherapy (SCRT) or concurrent chemoradiotherapy (CCRT) was used for 213 patients. Median age was 64 years (range: 27-88 years). Stage-III was the biggest stage group with 189 (88.7%) patients. Most patients with performance status (PS) 0 or 1 received CCRT, whereas most patients with PS 2 received RT alone (P < 0.001). CCRT, SCRT, and RT alone were used for 120 (56.3%), 24 (11.3%), and 69 (32.4%) patients, respectively. A third of all patients (32.4%) required either volumetric-modulated arc radiotherapy (VMAT) or tomotherapy. Median follow-up was 16 months. The median progression-free survival and median overall survival (OS) were 11 and 20 months, respectively. One-year OS and 2-year OS were 67.9% and 40.7%, respectively. Patients treated using CCRT lived significantly longer with a median survival of 28 months, compared with 13 months using SCRT and RT alone (P < 0.001). On multivariate analysis, OS was significantly affected by age, stage group, treatment approach, and response to treatment. CONCLUSION: RT including CCRT is feasible, safe, and well tolerated in our patient population and results in survival benefits comparable with published literature. CCRT should be considered for all patients with inoperable, locally advanced NSCLC, who are fit and have good PS.

Lymphoscintigraphy combined with single-photon emission computed tomography-computed tomography (SPECT-CT): A very effective imaging approach for identification of the site of leak in postoperative chylothorax.

Post operative chylothorax is a known complication of various thoracic surgeries. It needs identification of precise site of leak in the thoracic duct. Lymphosicintigraphy can identify chyle leak but cannot delineate exact site of leak. SPECT-CT is precise in anatomic localisation and hence SPECT-CT should be combined with every lymphoscintigraphy in evaluation of clinically suspected case of post operative chylothorax. We report such a case.

Tuberculosis nearly preventing a curative resection for colorectal liver metastasis: A case report.

Perihepatic lymph node involvement portends a poor prognosis, and is reported to be the most important prognostic factor following R0 resection of colorectal liver metastases. Tuberculous lymphadenitis is one of the common presentations of tuberculosis and is often diagnosed only after histopathological confirmation. In this patient, a frozen section revealing tuberculosis in the perihepatic nodes allowed us to proceed with the curative liver resection.

An ideal suture for midline abdominal closure?

BACKGROUND: Within the last decade the customary trend of using non absorbable sutures has changed, with numerous studies and meta-analyses advocating the use of slowly absorbable sutures, claiming comparable wound strength with significantly lower incidence of wound complications. It was the objective of this randomized clinical trial to compare two universally accepted suture materials, the non-absorbable Nylon and the slowly absorbable Polydioxanone for midline abdominal closure in the Indian context. METHOD: 64 patients undergoing midline laparotomy were allocated, using block randomization, to mass closure of the abdominal wall with continuous polyamide (34 patients) or continuous polydioxanone (30 patients). RESULTS: There was an alarmingly higher incidence of wound dehiscence in the PDS group requiring secondary suturing (Nylon 0; PDS 5). Mid-way through the trial, an interim analysis was performed which revealed an unacceptably high incidence of wound dehiscence in the PDS group. This necessitated a premature curtailment of the study. There was, however, a statistically significantly higher incidence of scar pain in the Nylon group (Nylon 9; PDS 1). CONCLUSION: There is a need for a study with larger series, and PDS as a choice of suture for midline wound closure cannot be recommended.
