Abstract
BACKGROUND Retroperitoneal tumours arising from the inferior vena cava (IVC) are rare tumours often requiring large vessel resection for complete surgical excision. Limited exposure to such tumours often discourages surgeons from offering surgical resection to these patients, depriving them of the only potentially curative modality. We present here the surgical technique for resection of a large IVC sarcoma without IVC reconstruction. METHODS A 53-year-old lady presented with a large retroperitoneal sarcoma encasing the infra-hepatic IVC with tumour thrombus extension into the hepatic cloaca as well as the left renal vein. Surgical resection was planned as the disease remained stable after 2 cycles of neoadjuvant chemotherapy with adriamycin and ifosfamide. RESULTS Complete surgical excision of the tumour was achieved by performing a resection of the entire length of infra-hepatic IVC and right kidney, without IVC reconstruction. Left renal vein was divided after careful preservation of a draining collateral. Tumour thrombus was extracted from the hepatic cloaca, and proximal IVC stump closure was achieved with preservation of right hepatic vein insertion. Total blood loss during the procedure was 2300 mL, and the patient recovered without compromise of renal function or development of lower limb oedema. CONCLUSION IVC resection without reconstruction can be safely performed for large retroperitoneal sarcomas involving major vascular structures. Familiarity with the retroperitoneal, retro-hepatic and supra-hepatic anatomy is paramount to achieving good surgical outcomes.

Abstract
BACKGROUND In India, as elsewhere, the incidence of gall-bladder cancer (GBC) is substantially higher in women than in men. Yet, the relevance of reproductive factors to GBC remains poorly understood. METHODS We used logistic regression adjusted for age, education and area to examine associations between reproductive factors and GBC risk, using 790 cases of histologically confirmed GBC and group-matched 1726 visitor controls. We tested the interaction of these associations by genetic variants known to increase the risk of GBC. RESULTS Parity was strongly positively associated with GBC risk: each additional pregnancy was associated with an ∼25% higher risk {odds ratio [OR] 1.26 [95% confidence interval (95% CI) 1.17-1.37]}. After controlling for parity, GBC risk was weakly positively associated with later age of menarche [postmenopausal women, OR 1.11 (95% CI 1.00-1.22) per year], earlier menopause [OR 1.03 (95% CI 1.00-1.06) per year] and shorter reproductive lifespan [OR 1.04 (95% CI 1.01-1.07) per year], but there was little evidence of an association with breastfeeding duration or years since last pregnancy. Risk alleles of single-nucleotide polymorphisms in the ABCB4 and ABCB1 genetic regions had a multiplicative effect on the association with parity, but did not interact with other reproductive factors. CONCLUSIONS We observed higher GBC risk with higher parity and shorter reproductive lifespan, suggesting an important role for reproductive and hormonal factors.

Abstract
The Gallbladder Reporting and Data System (GB-RADS) ultrasound (US) risk stratification is proposed to improve consistency in US interpretations, reporting, and assessment of risk of malignancy in gallbladder wall thickening in non-acute setting. It was developed based on a systematic review of the literature and the consensus of an international multidisciplinary committee comprising expert radiologists, gastroenterologists, gastrointestinal surgeons, surgical oncologists, medical oncologists, and pathologists using modified Delphi method. For risk stratification, the GB-RADS system recommends six categories (GB-RADS 0-5) of gallbladder wall thickening with gradually increasing risk of malignancy. GB-RADS is based on gallbladder wall features on US including symmetry and extent (focal vs. circumferential) of involvement, layered appearance, intramural features (including intramural cysts and echogenic foci), and interface with the liver. GB-RADS represents the first collaborative effort at risk stratifying the gallbladder wall thickening. This concept is in line with the other US-based risk stratification systems which have been shown to increase the accuracy of detection of malignant lesions and improve management.

Abstract
BACKGROUND Inferior vena cava (IVC) leiomyosarcomas (LMS) are a rare group of retroperitoneal tumors. R0 surgical resection is the only curative modality of treatment. IVC resection for retroperitoneal sarcoma is a complex surgery with no definitive guidelines for reconstruction. METHODS Retrospective review of all patients who underwent surgical resection of primary leiomyosarcoma of the IVC requiring resection from 2010 to 2020 at our tertiary care center was performed. RESULTS Among 24 patients who required IVC resection for LMS, only 7 (29%) required reconstruction of IVC. According to Clavien-Dindo classification, there was one grade 3 or more morbidity and 1 post-operative mortality. Seventeen patients underwent R0 resection whereas 7 patients had R1 resection on final histopathology. At a median follow-up of 25 months (range 8-91 months), the median OS was 40 months with median DFS of 28 months. Two patients presented with local recurrence while 13 patients developed systemic recurrence on follow-up. CONCLUSION Careful preoperative multidisciplinary planning can make IVC resection without reconstruction feasible with acceptable perioperative morbidity, mortality, and oncological outcomes for IVC LMS.

Abstract
BACKGROUND Gallbladder cancer (GBC) is the sixth most common gastrointestinal malignancy with poor prognosis. Enhanced Recovery Pathway (ERP) is associated with improved outcomes following abdominal surgical procedures. Currently, there is no study evaluating ERP in patients undergoing GBC surgery. The objective was to assess compliance with ERP elements and evaluate its impact on postoperative outcomes. METHODS Prospective study conducted from February 2014-2019, including elective GBC surgery. Team was educated prior to ERP implementation. Compliance with the protocol, functional gastrointestinal (GI) recovery, mobilisation, and postoperative outcomes were recorded. Impact of degree of compliance (more or less than 80%) with ERP and postoperative outcomes was evaluated. RESULTS In 408 patients, compliance with ERP was 84.6% (53.8-100%). Compliance >80% with ERP elements was observed in 245 patients (60%). Patients with >80% compliance had lower rate of minor (18.8% vs. 27%, p = 0.050) and significantly less major (0.8% vs. 6.1%, p = 0.002) and postoperative stay (5.84 ± 4.86 vs. 7.55 ± 6.6 days, p < 0.001) and earlier functional GI recovery. Intraoperative blood loss more than 600 ml, lower compliance (<80%) with ERP and preoperative albumin independently predicted postoperative complications. CONCLUSION This study demonstrates safety and efficacy of enhanced recovery pathway in gallbladder cancer. Higher compliance with the pathway was associated with significantly improved postoperative outcomes following gallbladder cancer surgery.

Abstract
AIM To assess the overall survival and determine whether pre-TARE shunt fraction, tumor volume and tumor marker impact the outcome. METHODS This is a retrospective study of 75 patients who were referred for 90Y-glass microsphere radioembolisation by a joint clinic decision between 1 January 2010 and 31 December 2014. All patients underwent pre-TARE CECT and 99mTc-MAA lung shunt fraction (LSF) imaging. RESULTS Overall survival was 19 months for hepatocellular carcinoma (HCC) and 24 months for metastatic colorectal carcinoma. For hepatocellular carcinoma-LSF higher than 6.51 % was predictive of significantly decreased survival (P value 0.00). A progressive disease in survival was observed as LSF increased from less than 6.51 % to more than 20%. Tumor volume and tumor marker did show correlation with patient outcomes. For metastatic colorectal carcinoma-LSF and tumor marker did not show significant correlation with survival and tumor volume showed significant correlation with survival with P value of 0.049.

Abstract
BACKGROUND AND AIMS The role of Alfa-fetoprotein (AFP) in the management of hepatocellular carcinoma (HCC) is still debated, with differences in recommendations between international guidelines. We analyzed the relationship of the clinicopathological profile, prognostic features, and survival outcomes with baseline serum AFP levels in patients with HCC. METHODS Retrospective analysis of a prospectively accrued dataset of consecutive HCC patients was done. RESULTS 508 treatment naive patients were included in the analysis. AFP at presentation was normal (<10 ng/ml) in 18% patients. Patients with very high AFP (>400 ng/ml) had poor hepatic reserves (higher mean serum bilirubin, AST, ALT, INR, and lower mean albumin) and advanced disease at presentation (higher incidence of extrahepatic metastasis, and less proportion of patients with well-differentiated tumors). AFP >400 ng/ml was an independent predictor for presence of portal vein tumor thrombosis (PVTT) (OR, 4.08; 95% CI, 2.34-7.12; P < 0.001), higher tumor size (OR, 2.19; 95% CI, 1.36-3.54, P = 0.001) and advanced BCLC stage (OR, 4.19; 95% CI, 2.51-7.03; P < 0.001). Two-third of patients with small HCC (MTD <3 cm) and more than half with early-stage HCC (BCLC stage 0/A) had elevated AFP levels. No significant relationship was seen between overall survival (OS) and baseline AFP in patients who underwent surgery, but median OS in patients subjected to nonsurgical therapies was 19.4,10.5 and 5.7 months in patients having AFP <10 ng/ml, 10-400 ng/ml and >400 ng/ml respectively (P = 0.003). AFP >400 ng/ml was an independent predictor of survival in patients receiving any form of therapy (HR = 2.23; 95% CI = 1.19-4.18, P = 0.012). CONCLUSION AFP as a biomarker still has a significant role to play in the management of HCC patients and is here to stay till the search for an ideal biomarker in HCC is over.

Abstract
Background This phase I dose de-escalation study aimed to assess the tolerability, safety, pharmacokinetics (PK), and efficacy of sequentially decreasing doses of sorafenib in combination (SAM) with atorvastatin (A, 10 mg) and metformin (M, 500 mg BD) in patients with advanced hepatocellular carcinoma (HCC). Methods Patients were enrolled in 1 of 4 sequential cohorts (10 patients each) of sorafenib doses (800 mg, 600 mg. 400 mg, and 200 mg) with A and M. Progression from one level to the next was based on prespecified minimum disease stabilization (at least 4/10) and upper limits of specific grade 3-5 treatment-related adverse events (TRAE). Results The study was able to progress through all 4 dosing levels of sorafenib by the accrual of 40 patients. Thirty-eight (95%) patients had either main portal vein thrombosis or/and extra-hepatic disease. The most common grade 3-5 TRAEs were hand-foot-syndrome (grade 2 and grade 3) in 3 (8%) and transaminitis in 2 (5%) patients, respectively. The plasma concentrations of sorafenib peaked at 600 mg dose, and the concentration threshold of 2400 ng/mL was associated with higher odds of achieving time to exposure (TTE) concentrations >75% centile (odds ratio [OR] = 10.0 [1.67-44.93]; P = .01). The median overall survival for patients without early hepatic decompensation (n = 31) was 8.9 months (95% confidence interval [CI]: 3.2-14.5 months). Conclusion The SAM combination in HCC patients with predominantly unfavorable baseline disease characteristics showed a marked reduction in sorafenib-related side effects. Studies using sorafenib 600 mg per day in this combination along with sorafenib drug level monitoring can be evaluated in further trials. (Trial ID: CTRI/2018/07/014865).

Abstract
PURPOSE The data on the prognostic significance of red cell distribution width (RDW) in gallbladder cancers is sparse, especially in the potentially resectable cohort of patients. The aim was to assess the prognostic significance of RDW in gallbladder cancer patients undergoing surgery. METHODS Retrospective analysis of prospectively maintained database of gallbladder cancer patients undergoing surgery at a tertiary cancer institute from 2010 till 2018. Baseline values were collected. Patients were grouped as per the median RDW value and compared. Survival analysis was done using the Kaplan Meier method. RESULTS A total of 605 patients were included. The median follow up period was 23 months (range: 6-120 months). The median value of RDW was 14. Comparison between RDW > 14 and RDW < 14 groups showed no difference in outcomes. RDW did not predict overall survival or recurrences. However, in combined stages II and III, a statistically significant improvement in OS and DFS (p < 0.001) was noted in the RDW < 14 group. CONCLUSION RDW did not predict recurrence or survival in potentially resectable gallbladder cancer patients. However, in the subset of stages II and III in combination, lower RDW value was associated with better outcomes. More prospective studies are needed to conclusively establish the prognostic value of RDW.

Abstract
Central liver tumors often require extended hepatectomy or a central hepatectomy with complex biliary reconstructions. Extended resections are prone to higher chances of post-operative liver failure, while the resections mandating reconstructions run a risk of biliary leaks. Non-anatomical liver resections for these centrally located tumors provide a benefit of functional parenchymal preservation but a higher perceived risk of oncological inadequacy. This manuscript is an attempt to showcase author's technique of parenchymal sparing liver resection for central located liver tumor without the need for any biliary reconstruction while ensuring oncological adequacy during the conduct of the procedure.

Abstract
Ewing’s sarcoma (ES)/primitive neuroectodermal tumors (PNETs) are a rare group of tumors commonly arising from bones, uncommonly from soft tissues, and rarely from abdomen. The aim of the study was to analyze the outcome (recurrence-free survival[RFS]), patient characteristics, role of FDG-PET (fluorodeoxyglucose positron emission tomography) computerized scan, chemotherapy and radiation, and prognostic factors. We retrospectively studied patients diagnosed with abdominal ES/PNET and treated surgically between June 2005 and November 2019. Ten patients were included in the study, with a median age of 36.5 years (19–46 years). The median follow-up was 25 months (3–178 months). The site of origin was the retroperitoneum, small bowel, and abdominal wall in six, two, and two patients, respectively. 70% of patients were treated with induction chemotherapy. R0 resection was achieved in 90% of patients. With chemotherapy, there was significant reduction in tumor size (p = 0.034) with non-significant reduction in SUV max (p = 0.31). The 1- and 2-year RFS were 88.90% and 76.20%, respectively. Pathological peritoneal metastasis and ability to achieve R0 resection were prognostic factors affecting RFS. These patients must be offered multimodality treatment. Induction chemotherapy significantly reduces the tumor size. Pathological peritoneal metastasis and ability to achieving R0 resection significantly affect survival.

Abstract
Background Biliary tract cancers (BTCs) are a rare group of cancers with limited data with respect to advanced unresectable cholangiocarcinoma (CCA). Materials and Methods The study is a retrospective study of patients with advanced unresectable/metastatic CCA, who received first-line palliative chemotherapy (CT1) from January 2014 to March 2019 at the Tata Memorial Hospital, Mumbai. Baseline clinical characteristics, chemotherapeutic regimens, and toxicities were evaluated. Results One hundred and forty patients satisfied criteria for evaluation. Median age of the entire cohort was 57 years (range: 32-80). There were 87 patients (62.1%) with intrahepatic CCA, 35 patients (25%) with perihilar CCA, and 14 patients (10%) with distal CCA. One hundred and twelve patients (80%) had metastatic disease at presentation. Commonest CT1 regimens were gemcitabine-cisplatin (GC) in 89 patients (63.5%) and gemcitabine-oxaliplatin (GO) in 34 patients (24.3%). Sixty-three patients (45%) received second-line chemotherapy. With a median follow-up of 27 months, median progression-free survival for the entire cohort was 7.56 months (95% confidence interval [CI]: 6.23-8.88), and median OS was 12.16 months (95% CI: 10.08-14.24). Common chemotherapy-related grade 3/4 side effects included vomiting in 25 patients (17.9%), diarrhea in 23 patients (16.4%), and thrombocytopenia in 22 patients (15.7%). Conclusion The current study in advanced CCAs is the largest of its nature from India. The common regimens used as first line were GC and GO. Tolerance and overall survival appear similar to previously published data.

Abstract
BACKGROUND Presence of jaundice in gallbladder carcinoma (GBC) is considered a sign of inoperability with no defined treatment pathways. METHODS Retrospective analysis of all surgically treated GBC patients from January 2010 to December 2019 was performed for evaluating etiology of obstructive jaundice, resectability, postoperative morbidity, mortality, disease-free survival (DFS) and overall survival (OS). RESULTS Out of 954 patients, 521 patients (54.61%) were locally advanced gallbladder carcinoma (LAGBC: Stage III and IV) and 113 patients (11.84%) had jaundice at presentation. Thirty-four (30%) patients had benign cause of obstructive jaundice. Median OS of the whole cohort (n=113) was 22 months (16.5-27.49 months) with resectability rate of 62% (70/113). Median OS of curative resection group (n=70) was 32 months and DFS was 25 months. Treatment completion was achieved in 30% (n= 21/70) patients with median OS of 46 months and median DFS of 27 months. Isolated bile duct infiltration subgroup fared the best with median OS of 74 months with a 5-year survival of 66.7%. CONCLUSION Surgical resection as a part of multimodality treatment improves survival in carefully selected locally advanced gallbladder cancer patients with jaundice. Early introduction of systemic therapy is the key in the management of this disease with aggressive tumor biology.

Abstract
BACKGROUND The overall survival (OS), disease-free survival (DFS) and complications after liver resections is unsatisfactory. Cancer-related malnutrition and inflammation have an effect on survival but not studied/not clear on postoperative complications. METHODS We retrospectively analyzed prospectively maintained database of 309 patients. The outcome variables included complications in terms of Clavien-Dindo (CD) Score, OS and DFS; We studied effect of preoperative albumin globulin ratio (AGR), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and aspartate transaminase to platelet ratio index (APRI) and dynamic change from pre-operative to postoperative value (Delta-AGR, Delta-NLR, Delta-PLR and Delta-APRI) on complications, OS and DFS. RESULTS Total 98 patients (31.71%) had postoperative complications. Fifty patients had CD 1 & 2 and 35 (11.33%) had CD 3 & 4, and 13 (4.12%) had mortality (CD 5). Low AGR, high NLR, high PLR and high Delta-AGR and high Delta-APRI predicted increased major complications. Preoperative high NLR predicted worse OS and low AGR predicted worse OS and DFS. Delta-APRI showed trends towards worse OS and DFS. CONCLUSION These serum inflammatory markers can predict immediate postoperative complications. Preoperative AGR and preoperative NLR can predict survival after liver resections. High Delta-AGR, which is a new entity, is predicting more postoperative complications and needs further detailed studies.

Abstract
This document aims to assist oncologists in making clinical decisions encountered while managing their patients with hepatocellular carcinoma (HCC), specific to Indian practice, based on consensus among experts. Most patients are staged by Barcelona Clinic Liver Cancer (BCLC) staging system which comprises patient performance status, Child-Pugh status, number and size of nodules, portal vein invasion and metastasis. Patients should receive multidisciplinary care. Surgical resection and transplant forms the mainstay of curative treatment. Ablative techniques are used for small tumours (<3 cm) in patients who are not candidates for surgical resection (Child B and C). Patients with advanced (HCC should be assessed on an individual basis to determine whether targeted therapy, interventional radiology procedures or best supportive care should be provided. In advanced HCC, immunotherapy, newer targeted therapies and modern radiation therapy have shown promising results. Patients should be offered regular surveillance after completion of curative resection or treatment of advanced disease.

Abstract
Importance There is therapeutic uncertainty regarding use of combination or single-agent chemotherapy in the treatment of patients with gallbladder cancer who experience disease progression after first-line chemotherapy. Objective To compare the efficacy of capecitabine plus irinotecan (CAPIRI) vs irinotecan (IRI) alone in patients with advanced gallbladder cancer (GBC) who have disease progression after gemcitabine-based first-line treatment. Design, Setting, and Participants The GB-SELECT trial was a multicenter, open-label, phase 2, randomized clinical trial of CAPIRI vs IRI alone for treatment of gallbladder cancer in patients who had disease progression after prior gemcitabine-based chemotherapy.The study was carried out in 2 tertiary care institutions in India. Patients aged between 18 and 70 years with histopathologic diagnosis of adenocarcinoma gallbladder, advanced or metastatic disease, previous treatment with gemcitabine-based chemotherapy, adequate hematologic, liver, and renal functions, and ECOG performance status of 1 or less were included in the study between August 2018 and January 2020. The data were analyzed for this report with cutoff on May 19, 2020. Interventions Patients were randomized 1:1 to receive capecitabine, 1700 mg/m2 per day, on days 1 to 14 plus intravenous irinotecan, 200 mg/m2, on day 1 or intravenous irinotecan, 240 mg/m2, on day 1, in 21-day cycles until disease progression or unacceptable toxic effects. Main Outcomes and Measures The primary end point was overall survival (OS) at 6 months. The secondary end points were progression-free survival and quality of life. Results A total of 98 patients were randomized, 49 in each arm, with median (range) age of 51 (29-70) years, with 60 (61%) being women. In the CAPIRI vs IRI arms, the number of deaths at 6 months, 6-month OS, and median OS were 35, 34, 38.4% (95% CI, 24.2%-52.6%) and 5.16 (95% CI, 4.26-6.06) months vs 34, 29, 54.2% (95% CI, 39.4%-69.0%) and 6.28 (95% CI, 4.25-8.30) months, respectively, with a hazard ratio of 1.02 (95% CI, 0.64-1.49, P = .93). There were no chemotherapy-related deaths but more patients required dose modification in CAPIRI compared with the IRI arm (13 [27%] vs 4 [9%], respectively, P = .03). Conclusions and Relevance There was no significant difference in OS between treatment with capecitabine plus irinotecan or irinotecan alone among previously treated patients with gallbladder cancer. Single-agent irinotecan should be the preferred treatment option for such patients. Trial Registration CTRI/2017/10/010112.

Abstract
OBJECTIVE Patients with inoperable multilobar hepatocellular carcinoma (HCC) Barcelona Clinic Liver Cancer (BCLC) stage B, who have failed other liver-directed treatment options, are ideal candidates for transarterial radioembolization (TARE) with Yttrium-90 (Y-90)-labeled glass spheres. There is limited data regarding variables that impact the prognosis and outcome in these patients. 99mTc-MAA scan for lung shunt fraction (LSF) and 18F-FDG PET/CT are performed during initial workup. We, therefore, decided to assess the prognostic impact of LSF and metabolic parameters, such as maximum SUVmax, MTV and TLG in patients undergoing TARE for HCC. METHODS We retrospectively analyzed 64 patients of HCC, between January 2010 and December 2016, deemed suitable for TARE. Pre-TARE LSF was computed on 99mTc MAA scan, and SUVmax, MTV and TLG on fluoro-deoxyglucose positron emission tomography/computed tomography were measured using automated software by 3D region of interest. LSF and PET parameters were stratified using optimal cut-offs derived from receiver operating curve analysis. Survival curves for the groups were estimated using the Kaplan-Meier method and were compared using log-rank test. RESULTS Overall survival (OS) was 15 months. In univariate analysis, high LSF (greater than 7.19), MTV and TLG were statistically significant and were associated with poor OS. In multivariate analysis, TLG (P value 0.044), MTV (P value 0.290) and LSF (P value 0.010) were independent predictors of outcome, after adjustment for significant univariate variables. However, SUVmax was not statistically significant for OS. CONCLUSIONS LSF, MTV and TLG are significant independent prognostic indicators of outcome in patients undergoing TARE for HCC.

Abstract
BACKGROUND There is a lack of consensus on the ideal time interval and therapeutic value of revision surgery in patients with incidental gallbladder cancer (iGBC) in the context of multimodality management. PATIENTS AND METHODS Retrospective analysis of an institutional database of patients with iGBC who underwent surgery from January 2010 to December 2019 was performed. Patients who underwent upfront surgery were divided into four time interval groups: A, B, C, and D (< 6 weeks, 6-10 weeks, 10-14 weeks, and > 14 weeks, respectively). RESULTS A cohort of 517 patients planned for revision surgery was analyzed. Overall, 382 (73.9%) patients underwent upfront surgery while 135 (26.1%) were given neoadjuvant treatment. With median follow-up of 18 months, 2-year overall survival (OS) was 66% and disease-free survival (DFS) was 52.6%, with inferior survival outcomes observed with advancing stage and presence of residual disease on final histopathology. Propensity score-matched analysis after matching for pT stage of cholecystectomy specimen suggested a survival benefit for patients operated between 10 and 14 weeks in terms of OS (p = 0.049) and DFS (p = 0.006). Patients with locally advanced iGBC at presentation had superior OS when operated after neoadjuvant therapy [3-year estimated OS of 59.9% vs 32.3%, respectively (p = 0.001)]. CONCLUSIONS Revision surgery is at best the most accurate staging procedure guiding timely initiation of systemic therapy. Patients with iGBC operated between 10 and 14 weeks after initial cholecystectomy tend to have favorable survival outcomes, although this depends on final disease stage. Revision surgery should also be offered to all patients presenting at any later point of time, if deemed operable.

Abstract
Revision surgery with or without chemotherapy in the neoadjuvant or adjuvant setting remains the standard treatment for incidental gallbladder cancers (iGBCs). Over the years, researchers have retrospectively analyzed the surgical audits and tried to establish the perceived benefit and optimal timing for revision surgery. Patkar and colleagues have analyzed the outcomes for 517 patients with iGBC, concluding that there is no optimal timing for performing a revision surgery after initial cholecystectomy. Revision surgery is essentially the most accurate staging procedure and should be offered to patients at any time of presentation if they remain non-metastatic. Timely initiation of chemotherapy is the key to improving the outcomes for patients with this otherwise inherently aggressive disease.

Abstract
BACKGROUND Past history of gallstones is associated with increased risk of gallbladder cancer in observational studies. We conducted complementary observational and Mendelian randomization (MR) analyses to determine whether history of gallstones is causally related to development of gallbladder cancer in an Indian population. METHODS To investigate associations between history of gallstones and gallbladder cancer, we used questionnaire and imaging data from a gallbladder cancer case-control study conducted at Tata Memorial Hospital, Mumbai, Maharashtra, India (cases = 1,170; controls = 2,525). We then used 26 genetic variants identified in a genome-wide association study of 27,174 gallstone cases and 736,838 controls of European ancestry in an MR approach to assess causality. The association of these genetic variants with both gallstones and gallbladder cancer was examined in the gallbladder cancer case-control study. Various complementary MR approaches were used to evaluate the robustness of our results in the presence of pleiotropy and heterogeneity, and to consider the suitability of the selected SNPs as genetic instruments for gallstones in an Indian population. RESULTS We found a strong observational association between gallstones and gallbladder cancer using self-reported history of gallstones [OR = 4.5; 95% confidence interval (CI) = 3.5-5.8] and with objective measures of gallstone presence using imaging techniques (OR = 2.0; 95% CI = 1.5-2.7). We found consistent causal estimates across all MR techniques, with ORs for gallbladder cancer in the range of 1.3-1.6. CONCLUSIONS Our findings indicate a causal relationship between history of gallstones and increased risk of gallbladder cancer, albeit of a smaller magnitude than those found in observational analysis. IMPACT Our findings emphasize the importance of gallstone treatment for preventing gallbladder cancer in high-risk individuals.
