Analysis of 50 cases of solid pseudopapillary tumor of pancreas: Aggressive surgical resection provides excellent outcomes.

Eur J Surg Oncol 2019 02 8;45(2):187-191. Epub 2018 Sep 8.

Gastrointestinal and Hepato-Pancreato-Biliary Service, Department of Surgical Oncology, Tata Memorial Hospital, Mumbai, Maharashtra, 400012, India. Electronic address:

Introduction: This study reports the clinicopathological characteristics and the perioperative and long-term treatment outcomes after aggressive surgical resection in solid pseudopapillary tumor (SPT) of the pancreas performed at a high volume center for pancreatic surgery in India.

Materials And Methods: We analyzed a prospectively maintained database of the patients operated for SPT at Tata Memorial Hospital, India over a period of 11 years from February 2007 to February 2018.

Results: Fifty consecutive patients operated for SPT, during the study period were included. The median age at presentation was 24 years. Majority of the patients (43/50) were female (86%). Disease was predominantly localized in the head and uncinate process of pancreas (66%). Median tumor size was 7.7?cm (Range 1.6-15?cm). Tumor extent was radiologically defined as borderline resectable or locally advanced in 48% (n?=?24) patients. Forty-six major pancreatic resections were performed, which included 10 (21%) vascular resections, 2 synchronous liver metastasectomies, 1 multi visceral resection and 5 total pancreaticosplenectomies. Five of these resections were reoperations in patients deemed inoperable on exploration at other centers. R0 resection was achieved in 47 patients (98%). Postoperative major morbidity was 19% and there was no mortality. At a median follow-up of 29 months (Range, 1-121 months), all patients were alive without any recurrence.

Conclusion: Aggressive complete surgical resection of SPT achieves excellent long-term survival. Surgery, especially for large and borderline resectable tumors, can be potentially complex and should be performed at high-volume centers to provide the best chance of cure.

Pulmonary metastasectomy of colorectal cancer origin: Evaluating process and outcomes.

J Surg Oncol 2018 Dec 17;118(8):1292-1300. Epub 2018 Oct 17.

Department of Colorectal Surgical Oncology, Tata Memorial Centre, Mumbai, Maharashtra, India.

Background: This study was undertaken to evaluate the effect of change in policy of computed tomography (CT) scan of the thorax in staging and follow-up of colorectal cancer (CRC). Another objective was to review the outcomes following pulmonary metastasectomies (Pmets) and to determine the prognostic factors affecting outcomes.

Methods: This is a retrospective analysis from a prospective cohort database of patients, who underwent Pmet for CRC origin from August 2004 to February 2016. The outcome measures were number of Pmets per year, overall survival (OS), disease-free survival (DFS), and prognostic factors affecting survival.

Results: Of 71 patients, 38% (n?=?27) underwent Pmet before 2013 and 62% ( n?=?44) had surgery after 2013. The 2-year DFS after Pmet was 49.3% and estimated 5-year OS was 51.4% at a median follow-up of 28 months. There was a significant increase in number of Pmets/year ( P?=?0.0015), increased detection of synchronous pulmonary metastasis (PM) ( P?=?0.005), increased diagnosis of extra-pulmonary metastases (EPM) ( P?=?0.005), and improved OS ( P?=?0.026) after introduction of CT scan as staging tool. Site of primary tumor (colon) ( P?=?0.045), primary nodal stage ( P?=?0.009), and the presence of EPM ( P?=?0.01) were independent important prognostic factors affecting survival.

Conclusion: The CT scan of thorax as a baseline tool for staging and follow-up in CRC increases referral for pulmonary metastasectomy. Surgery achieves excellent prognosis and long-term survival outcomes in CRC with isolated PM and carefully selected patients with solitary liver metastasis.

Radical gastrectomy for gastric cancer at Tata Memorial Hospital.

Indian J Cancer 2017 Oct-Dec;54(4):605-608

GI and HPB Service, Department of Surgical Oncology, Tata Memorial Hospital, Mumbai, Maharashtra, India.

Aim: Tata Memorial Hospital is one of the high-volume tertiary care referral centers for gastric cancer (GC) in India. We aimed to analyze the outcomes after surgery for GC.

Patients And Methods: Data were collected from the prospective database maintained by the Gastrointestinal and Hepato-Pancreato-Biliary Division of the Department of Surgical Oncology at Tata Memorial Hospital, Mumbai, Maharashtra, India. All consecutive patients who underwent curative resection for adenocarcinoma of the stomach from January 2010 to December 2015 were included.

Results: A total of 580 patients underwent curative resection for adenocarcinoma of the stomach in the above mentioned time span. Distal tumors were more common and the tumor epicenter was at the distal body/antrum in 435 (75%) patients. One hundred eighty-two (31.3%) patients underwent upfront surgery and 398 patients (68.6%) were operated after receiving neoadjuvant chemotherapy. Surgical procedures included 371 distal/subtotal gastrectomies, 78 proximal, and 131 total gastrectomies. Overall median blood loss was 500 mL and intraoperative blood transfusion was required only in 10.5%. Median hospital stay was 8 days (range, 3-44). Postoperative major morbidity (Clavein-Dindo grade III/IV) was 8.9% and mortality was 1.5%. Median lymph node yield was 18 (range, 2-76). When perioperative outcomes were compared in the initial half of the study period (Period 1, 2010-2012) versus the later half (Period 2, 2013-2015), the median lymph node yield was found to be better in the later half (17 vs. 19) along with reduction in the median hospital stay (16 vs. 11 days). At a median follow-up of 36 months (range, 3-225 months), overall 5-year survival was 51.9%. The disease-free survival at 5 years was 46.9%.

Conclusion: Results from our study indicate that, with increasing hospital volumes, the median lymph node yield after D2 gastrectomy improves and the median hospital stay is reduced. Surgery for GCs in high-volume centers might result in improved perioperative outcomes.
