Abstract
OBJECTIVE The TORPEDO (CTRI/2018/12/016789) is the single-arm, prospective, interventional study evaluating the role of a total parietal peritonectomy (TPP) in patients undergoing interval cytoreductive surgery (iCRS). In this manuscript, we report the perioperative outcomes and platinum resistant recurrence (PRR) in 218 patients enrolled in the study. METHODS A TPP was performed in all patients undergoing iCRS irrespective of the residual disease extent. hyperthermic intraperitoneal chemotherapy (HIPEC) was performed as per the clinician's discretion with 75 mg/m² of cisplatin. Maintenance therapy was also used at the discretion of the treating clinicians. RESULTS From 9th December 2018 to 31st July 2022 (recruitment complete), 218 patients were enrolled at 4 medical centers in India. The median surgical peritoneal cancer index was 14 and a complete gross resection was achieved in 95.8%. HIPEC was performed in 130 (59.6%) patients. The 90-day major morbidity was 17.4% and 2.7% patients died within 90 days of surgery. Adjuvant chemotherapy was delayed beyond 6 weeks in 7.3%. At a median follow-up of 19 months (95% confidence interval [CI]=15.9-35 months), 101 (46.3%) recurrences and 19 (8.7%) deaths had occurred. The median progression-free survival was 22 months (95% CI=17-35 months) and the median overall survival (OS) not reached. Platinum resistant recurrence was observed in 6.4%. The projected 3-year OS was 81.5% and in 80 patients treated before may 2020, it was 77.5%. CONCLUSION The morbidity and mortality of TPP with or without HIPEC performed during iCRS is acceptable. The incidence was of PRR is low. Early survival results are encouraging and warrant conduction of a randomized controlled trial comparing TPP with conventional surgery.

Abstract
A previous report from the Indian HIPEC registry showed acceptable early survival and morbidity in patients undergoing cytoreductive surgery (CRS) + / - hyperthermic intraperitoneal chemotherapy (HIPEC). The goal of this retrospective study was to evaluate the long-term outcomes in these patients. Three hundred seventy-four patients treated from December 2010 to December 2016 and enrolled in the Indian HIPEC registry were included. All patients had completed 5 years from the date of surgery. The 1-, 3-, 5- and 7-year progression-free (PFS) and overall survival (OS) and factors affecting these were evaluated. The histology was epithelial ovarian cancer in 209 (46.5%), pseudomyxoma peritonei (PMP) in 65 (17.3%) and colorectal cancer in 46 (12.9%) patients. The peritoneal cancer index (PCI) was ≥ 15 in 160 (42.8%). A completeness of cytoreduction (CC) score of 0/1 resection was obtained in 83% (CC-0-65%; CC-1-18%). HIPEC was performed in 59.2%. At a median, follow-up of 77 months (6-120 months), 243 (64.9%) patients developed recurrence, and 236 (63%) died of any cause; 138 (36.9%) were lost to follow-up. The median OS was 56 months (95% CI 53.42-61.07), and the median PFS was 28 months (95% CI 37.5-44.4). The 1-, 3-, 5- and 7-year OS was 97.6%, 63%, 37.7% and 24% respectively. The 1-, 3-, 5- and 7-year PFS was 84.8%, 36.5%, 27.3% and 22% respectively. The use of HIPEC (p = 0.03) and PMP of appendiceal origin (p = 0.01) was independent predictors of a longer OS. CRS + / - /HIPEC may achieve long-term survival in patients with PM from different primary sites in the Indian scenario. More prospective studies are needed to confirm these findings and identify factors influencing long-term survival.

Abstract
Objective To evaluate the feasibility, tolerance, and efficacy of OMCT (oral metronomic chemotherapy) after CRS + HIPEC for peritoneal mesothelioma in patients with poor prognostic factors: PCI > 20, incomplete CRS, poor performance status, or progression on systemic chemotherapy. Methods A retrospective analysis of patients undergoing CRS + HIPEC for peritoneal mesothelioma and receiving OMCT for poor risk factors. Results Sixteen patients underwent CRS + HIPEC between 2013 and 2017. The median PCI was 31.5. Complete cytoreduction (CC-0/1) was obtained in 8 patients (50%). All 16 received HIPEC except one patient with baseline renal dysfunction.Thirteen patients had PCI > 20 where only 5 had CC-0/1. Of 8 suboptimal cytoreduction (CC-2/3), 7 received OMCT (6 for progression on chemotherapy and one for mixed histology). Three patients had PCI < 20 and all had CC-0/1 clearance. Only one received OMCT for progression on adjuvant chemotherapy. Patients receiving OMCT for progression on adjuvant chemotherapy (ACT) were in poor PS.The median follow-up was 13.4 months. Five are alive with the disease (three are on OMCT). Six are alive without disease (2 are on OMCT). The mean OS was 24.3 months and the mean DFS was 18 months. Outcomes were similar between CC-0/1 and CC-2/3 groups, OMCT vs no OMCT groups.All patients receiving OMCT for progression on neoadjuvant chemotherapy had better survival (alive at 12, 20, 32, 36 months) compared to those receiving OMCT for progression on the ACT (p = 0.012). Conclusion OMCT is a good alternative in high-volume peritoneal mesothelioma with incomplete cytoreduction and progression on chemotherapy. OMCT may improve outcomes in these scenarios when started early.

Abstract
Pleural spread occurs in pseudomyxoma peritonei (PMP) in less than 10% of the patients and is treated by thoracic cytoreductive surgery with or without hyperthermic intrathoracic chemotherapy (HITOC). It is performed both for symptom palliation and disease control and includes pleurectomy and decortication and wedge and segmental lung resections. So far, only unilateral spread treated with a thoracic cytoreductive surgery (CRS) has been reported in literature. We report a patient with bilateral thoracic PMP following a complete abdominal CRS and hyperthermic intraperitoneal chemotherapy (HIPEC) who was treated with bilateral staged thoracic CRS and subsequently had a 4th CRS for abdominal disease. The staged procedure was performed as she was symptomatic due to the thoracic disease and there was disease on all pleural surfaces. HITOC was not performed. Both procedures were uneventful with no major morbidity. The patient is currently disease free nearly 84 months after the first abdominal CRS and 60 months after the second thoracic CRS. Thus, an aggressive CRS in the thorax in patients with PMP can result in a prolongation of survival while preserving the quality of life if the abdominal disease is controlled. A thorough understanding of the disease biology and surgical expertise are both essential for selecting the right patients for these complex procedures and achieving good short- and long-term outcomes.

Abstract
Taxanes have a favorable pharmacokinetic profile for intraperitoneal application. We report our initial experience with taxane-PIPAC (pressurized intraperitoneal chemotherapy) for unresectable peritoneal metastases from different primary sites in terms of safety, feasibility, response rate, and conversion to resectability. In this retrospective study, PIPAC was performed alone or in combination with systemic chemotherapy. Paclitaxel was used as a single agent, whereas docetaxel was used in combination with cisplatin-adriamycin or oxaliplatin-adriamycin. From December 2019 to December 2021, 47 patients underwent 82 PIPAC procedures (1 PIPAC in 55.3%, 2 in 29.7%, 3 in 14.8%). The most common primary sites were ovarian cancer (31.9%), gastric cancer (23.4%), and colorectal cancer (21.2%). Docetaxel-cisplatin-adriamycin was used in 33 (70.2%) patients, docetaxel-oxaliplatin-adriamycin in 12 (25.5%), and paclitaxel alone in 2 (4.2%) patients. Grade 1-2 complications were observed in 24 (51%) and grade 3-4 complications in 6 (12.7%) patients (8.5% of 82 PIPACs). 16/47 (34.0%) patients had a clinical response to PIPAC. The mean PCI was 25.9 ± 9.2 for the first PIPACs and 22.4 ± 9 for the subsequent PIPACs with an average reduction of 3.6 points [change in PCI ranged from - 14 to + 8]. The PRGS was 1/2 in 4/47 (8.5%) patients (19.0% patients with > 1 PIPAC). A reduction in ascites was observed in 35.4% presenting with ascites. Nine (19.1%) patients had conversion to operability leading to a subsequent cytoreductive surgery in 8 (17%) patients. PIPAC with docetaxel is feasible and safe. The role of PIPAC with both docetaxel and paclitaxel either alone or in combination with other drugs should be investigated in prospective studies.

Abstract
Background Aggressive locoregional therapies like hyperthemic intraperitoneal chemotherapy(HIPEC) and total parietal peritonectomy(TPP) have been used to delay recurrence in patients with advanced ovarian cancer undergoing interval cytoreductive surgery(CRS). The aim of this retrospective study was to evaluate the incidence of platinum resistant recurrence (PRR) and early recurrence (ER)(recurrence within 6 months and 1 year of the last dose of platinum based therapy, respectively) in patients undergoing interval CRS. The secondary goal was to study impact of each of these therapies on PRR and ER. Methods One-hundred and fifty-three patients undergoing interval CRS from July 2018 to June 2020 were included. The surgical strategy was to perform a TPP in which the entire parietal peritoneum is resected irrespective of the disease extent or a selective parietal peritonectomy (SPP) in which only the peritoneum bearing visible residual disease is resected. The use of HIPEC was at the discretion of the treating oncologists. Results The median surgical PCI was 15 [range, 0-37]. A CC-0 resection was obtained in 119 (77.7%) and CC-1 in 29 (18.9%) patients. Eighty-one (53%) patients had a TPP and 72 (47%) had SPP. HIPEC was performed in 98(64%) patients. Bevacizumab maintenance was administered to 31(19.6%) patients. No patients received PARP inhibitors during first-line therapy. PRR was observed in 8(5.2%) patients and ER in 30(19.6%). The respective incidences of PRR and ER were 4.9% and 16% in the TPP group, 4.1% and 23.6% in the SPP group, 9% and 20% in the no-HIPEC group and 3% and 19.3% in the HIPEC groups. On multivariate analysis, CC-0(p=0.014) resection and HIPEC(p=0.030) were independent predictors of a low ER. All patients with PR and 70% with ER had peritoneal recurrence with or without extra-peritoneal sites of recurrence. Conclusions The incidence of PRR and ER in this cohort was low as compared to historical data. This low incidence could be attributed to the use of aggressive locoregional therapies like TPP and HIPEC. In future, studies should be conducted to confirm these findings and evaluate the potential additive benefit of TPP and HIPEC coupled together as well as their combination with maintenance therapies.

Abstract
AIM The aim was to compare oncological and short-term outcomes between open and laparoscopic surgery in locally advanced rectal cancers. METHODS It is a retrospective analysis conducted in a high volume tertiary centre. Matching was carried out for nine variables, including preoperative factors, neoadjuvant treatment and sphincter preservation. RESULTS Both the open and laparoscopic surgery arms had 239 patients each. The distributions of pretreatment MRI T3, T4, circumferential resection margin (CRM) positive tumours, neoadjuvant long-course chemoradiation and sphincter preservation were 80.3%, 13.6%, 50%, 89% and 56.4% respectively. The mean number of nodes harvested (12.9 vs. 12.7, P = 0.716), pathological CRM positivity (6.3% in open vs. 5.4% in laparoscopic, P = 0.697) and distal resection margins were similar. The mean blood loss was higher in open surgeries (910 ml vs. 349 ml, P < 0.001). Anastomotic leaks and Clavien-Dindo Grade 3-4 complications were higher in the open arm than in the laparoscopy arm (5.9% vs. 1.7%, P = 0.024, and 12.5% vs. 6.7%, P = 0.015 respectively). The median postoperative hospital stay was significantly shorter in the laparoscopy arm (7 vs. 6, P = 0.015). In CRM positive and threatened cases, the measured outcomes were similar between the two groups except for blood loss which was significantly higher in the open surgery (872 vs. 379, P = 0.000). CONCLUSIONS In high volume centres, in the hands of experienced colorectal surgeons, laparoscopic rectal surgery is oncologically safe in locally advanced rectal cancers and has lesser morbidity and shorter hospital stay than open surgery. In CRM positive and threatened cases the laparoscopic surgery showed less blood loss compared to open surgery, while other outcome measures were similar to open surgery.

Abstract
INTRODUCTION Despite optimal patient selection and surgical effort, recurrence is seen in over 70% of patients undergoing cytoreductive surgery (CRS) for peritoneal metastases (PM). Apart from the Peritoneal Cancer Index (PCI), completeness of cytoreduction and tumour grade, there are other factors like disease distribution in the peritoneal cavity, pathological response to systemic chemotherapy (SC), lymph node metastases and morphology of PM which may have prognostic value. One reason for the underutilisation of these factors is that they are known only after surgery. Identifying clinical predictors, specifically radiological predictors, could lead to better utilisation of these factors in clinical decision making and the extent of peritoneal resection performed for different tumours. This study aims to study these factors, their impact on survival and identify clinical and radiological predictors. METHODS AND ANALYSIS There is no therapeutic intervention in the study. All patients with biopsy-proven PM from colorectal, appendiceal, gastric and ovarian cancer and peritoneal mesothelioma undergoing CRS will be included. The demographic, clinical, radiological, surgical and pathological details will be collected according to a prespecified format that includes details regarding distribution of disease, morphology of PM, regional node involvement and pathological response to SC. In addition to the absolute value of PCI, the structures bearing the largest tumour nodules and a description of the morphology in each region will be recorded. A correlation between the surgical, radiological and pathological findings will be performed and the impact of these potential prognostic factors on progression-free and overall survival determined. The practices pertaining to radiological and pathological reporting at different centres will be studied. ETHICS AND DISSEMINATION The study protocol has been approved by the Zydus Hospital ethics committee (27 July, 2020) and Lyon-Sud ethics committee (A15-128). TRIAL REGISTRATION NUMBER CTRI/2020/09/027709; Pre-results.

Abstract
BACKGROUND AND AIM The greater omentum(GO) is a common site of residual disease in patients receiving neoadjuvant chemotherapy for advanced epithelial ovarian cancer. The presence of tumor in the GO could predict presence of disease in other peritoneal regions. The goal of this study was to perform a correlation between the greater-omentum lesion-score(GOLS) and presence of disease in different peritoneal regions and determine its potential utility in guiding interval cytoreductive surgery(CRS). METHODS This prospective study included 134 patients undergoing interval CRS from July 1, 2018 to June 30, 2020. Each region of Sugarbaker's Peritobneal Cancer Index(PCI) was given a lesion score(LS) from 0 to 3 according to the diameter of the largest tumor in the region. The GOLS was recorded separately from other structures in the region. Correlation between the GOLS and surgical and pathological LS in each region was performed. RESULTS As the GOLS increased, the incidence of disease(surgical LS) in other regions of the peritoneal cavity increased. Receiver operating characteristic(ROC) curves showed area under curve more than 80% for regions 1-2 and 7-8 indicating a high probability of disease in these regions in patients with GOLS 1-3. The positive predictive value(PPV) of preoperative imaging for GOLS was 95.7%. No cut-off of the GOLS could predict presence of disease on pathology with more than 70% accuracy. CONCLUSIONS Presence of disease in the GO warrants performing upper abdominal exploration and/or cytoreduction and interval CRS should be planned accordingly in these patients. Imaging has a high PPV in detecting disease in the GO.

Abstract
OBJECTIVES To compare clinical outcomes following total and selective peritonectomy performed during interval cytoreductive surgery (CRS) for stage IIIC/IVA serous epithelial ovarian cancer. METHODS In this retrospective study, extent of peritonectomy was classified as total parietal peritonectomy (TPP) which comprised of removal of the entire parietal peritoneum and the greater and lesser omenta or selective parietal peritonectomy (SPP) that included 1/>1 of parietal peritonectomies performed to resect sites of residual disease. A comparison of patient and disease characteristics, morbidity, mortality and survival outcomes between the two groups was made. RESULTS From January 2013 to December 2017, 79 patients underwent CRS (TPP-30, SPP-49) with or without intraperitoneal chemotherapy (IPC). The median PCI was 14 for TPP and 8 for SPP. The 90-day grade 3-4 morbidity (23.3% for TPP, 14.2% for SPP, p = 0.58) the 90-day mortality was similar (p = 0.58). The median disease free survival (DFS) was 37 months for SPP and 33 months for TPP (p = 0.47) and median overall survival (OS) not reached for both. The 3-year OS was 95% for TPP and 70.8% for SPP (p = 0.06). The only independent predictor of OS was grade 3-4 morbidity (p = 0.01) and not TPP (p = 0.09). Microscopic residual disease was seen in 23.3% with normal looking peritoneum in TPP group. CONCLUSIONS TPP was not associated with increased morbidity compared to SPP. There was a trend towards a longer OS in the TPP group and the finding of residual disease in 'normal looking' peritoneum' warrants prospective evaluation of the benefit of TPP in this setting.

Abstract
AIM The peritoneal cancer index (PCI) is one of the strongest prognostic factors in patients undergoing cytoreductive surgery (CRS) for colorectal peritoneal metastases. Using pathological evaluation, however, the disease extent differs in a large proportion of patients. Our aim was to study the correlation between the radiological (rPCI), surgical (sPCI) and pathological (pPCI) PCI in order to determine factors affecting the discordance between these indices and their potential therapeutic implications. METHOD From July 2018 to December 2019, 128 patients were included in this study. The radiological, pathological and surgical findings were compared. A protocol for pathological evaluation was followed at all centres. RESULTS All patients underwent a CT scan and 102 (79.6%) had a peritoneal MRI. The rPCI was the same as the sPCI in 81 (63.2%) patients and the pPCI in 93 (72.6%). Concordance was significantly lower for moderate-volume (sPCI 13-20) and high-volume (sPCI > 20) disease than for low-volume disease (sPCI 0-12) (P < 0.001 for sPCI; P = 0.001 for pPCI). The accuracy of imaging in predicting presence/absence of disease upon pathological evaluation ranged from 63% to 97% in the different regions of the PCI. The pPCI concurred with the sPCI in 86 (68.8%) patients. Of the nine patients with sPCI > 20, the pPCI was less than 20 in six. CONCLUSION The rPCI and sPCI both concurred with pPCI in approximately two thirds of patients. Preoperative evaluation should focus on the range in which the sPCI lies and not its absolute value. Radiological evaluation did not overestimate sPCI in any patient with high/moderate-volume disease. The benefit of CRS in patients with a high r/sPCI (> 20) who respond to systemic therapies should be prospectively evaluated.

Abstract
BACKGROUND Patients undergoing cytoreductive surgery for colorectal peritoneal metastases who have a pathologic complete response (pCR) to neoadjuvant chemotherapy experience a significantly longer survival than those with residual disease. This response is known only after surgery. This study aimed to examine clinical and radiologic predictors of a pCR. METHODS From July 2018 to December 2019, the study prospectively enrolled 120 patients. The clinical and radiologic findings were compared between patients with and without a pCR. A protocol for pathologic evaluation was followed. RESULTS A pCR was observed in 34 patients (28.3%). Receiver operating characteristic (ROC) curves showed that patients with a surgical Peritoneal Cancer Index (sPCI) of 3 or lower had an 80% probability of experiencing a pCR, and that patients with a radiologic PCI (rPCI) of 2 or lower had a 70% probability of experiencing a pCR. A pCR was correctly predicted for 47% of the patients by imaging and for 44.4% of the patients by surgical evaluation. The site of primary tumor, the timing of peritoneal metastasis (PM), histology, tumor marker positivity, and mutations in known poor prognostic genes (KRAS) did not differ between the patients with and those without pCR. The primary tumor showed residual disease in 23.5% and regional nodes in 26.4% of the patients with pCR. CONCLUSIONS The rPCI and sPCI concurred with a pCR in less than 50% of the patients. The patients with a lower PCI had greater concordance. An sPCI of 3 or lower was predictive of a pCR in 80% of the patients. The impact of KRAS mutations on pCR should be evaluated in a larger series. The predictors of pCR and response to systemic chemotherapy should be incorporated in prognostic scores used to select patients for surgery.

Abstract
INTRODUCTION Residual disease in 'normal appearing' peritoneum is seen in nearly 30% of the patients following neoadjuvant chemotherapy (NACT) for advanced ovarian cancer. The goal was to study the sequence of response in different regions, the commonest sites of occult residual disease, its incidence in different peritoneal regions and the potential therapeutic implications of these. METHODS This was a prospective multi-centre study (July 2018-June 2019). Pathological evaluation of cytoreductive surgery specimens was performed according to a fixed protocol. Prevalence of residual disease in different regions was used to study patterns of response and distribution of residual disease. RESULT In 85 patients treated between July 2018 to June 2019, microscopic disease in 'normal appearing' peritoneal regions was seen in 22 (25.2%) and in normal peritoneum around tumor nodules in 30 (35.2%) patients. Regions 4 and 8 of Sugarbaker's PCI had the highest incidence of occult disease and regions 9 and 10 the lowest. The response to chemotherapy occurred in a similar manner in over 95%- the least common site of residual disease was the small bowel mesentery, followed by upper regions (regions 1-3), omentum and middle regions (regions 0, 4, 8), lower regions (regions 5-7) and lastly the ovaries. CONCLUSIONS During interval CRS, based on the disease mapping provided in this manuscript, regions that have a high probability of residual disease should be explored and dissected. Complete resection of involved the peritoneal region can completely address the occult disease. The role of resection of the entire region as well as 'normal appearing' parietal peritoneal regions should be prospectively evaluated.

Abstract
BACKGROUND Total parietal peritonectomy (TPP) removes areas of "normal-appearing" parietal peritoneum bearing microscopic residual disease and has the potential to improve survival of patients undergoing interval cytoreductive surgery (CRS) for advanced serous epithelial ovarian cancer. This report presents the morbidity outcomes for the first 50 patients enrolled in TORPEDO (CTRI/2018/12/016789), a prospective study. METHODS All the patients underwent a TPP during interval CRS. A surgical protocol that includes a description of the boundaries for each of the five peritonectomies was followed. The common toxicology criteria for adverse events (CTCAE) classification was used to record 90-day morbidity and mortality. RESULTS The median Peritoneal Cancer Index (PCI) for 50 patients was 15 (range, 5-37). A complete cytoreduction (CC-0 resection) was obtained in 80%, a CC-1 resection in 16%. A bowel resection was performed in 70% of the patients. Grade 3 or 4 complications were seen in 11 patients (22%), and one patient died within 90 days after surgery due to intraperitoneal hemorrhage. The most common complications were postoperative fluid collection requiring aspiration (n = 5), intraperitoneal hemorrhage (n = 2), abdominal wound dehiscence (n = 2), pseudo-obstruction (n = 1), urinary sepsis (n = 2), and ileostomy-related complications (n = 2). No bowel fistulas or anastomotic leaks occurred. Microscopic disease in 'normal appearing' peritoneum adjacent to tumor nodules was observed in 46% of the patients, and in regions given a lesion score of 0 in 34%. The parietal peritoneal regions (0-8) had a higher incidence of residual disease (p < 0.001) and occult disease (p < 0.001). CONCLUSIONS During interval CRS, TPP can be performed with acceptable morbidity and mortality. The pathologic findings further support this therapeutic rationale. Survival outcomes should determine the future role of such a procedure in routine clinical practice.

Abstract
BACKGROUND Selected patients with platinum sensitive recurrent ovarian cancer may benefit from cytoreductive surgery (CRS). The aim was to study the pattern of peritoneal involvement in these patients that has not been done before. METHODS A comparison was made between the surgical and pathological findings in 60 patients undergoing salvage CRS from July 2018 to December 2019. The sites of residual disease, correlation with surgical and pathological peritoneal cancer index (PCI), small bowel involvement and regional lymph node involvement were studied. RESULTS Fifty-eight (96.6%) had serous carcinoma and 2 (3.4%) clear cell carcinoma. The median surgical PCI (sPCI) was 7 [range 0-27] and median pathological PCI (pPCI) 4 [range 0-21]. CC-0 resection was performed in 81.6%. The upper regions (region 1,2,3) were the commonest sites of residual disease (63.3%) followed by lower regions (region 5,6,7) in 55.0%, middle regions (regions 0,4,8) in 53.3% and small bowel regions (regions 9-12) in 26.6%. Small bowel involvement was associated with a higher sPCI and pPCI (p < 0.001 for both). Regional nodes were involved in 46.6%. A pathological complete response was seen in 8 (13.3%) patients of which 2 had residual disease in regional nodes. Microscopic disease in 'normal appearing' peritoneum was seen in 21%. CONCLUSIONS The parietal peritoneum was the commonest site of recurrence. Small bowel involvement occurred late and was associated with more extensive disease. Regional lymph node involvement was seen nearly 50% and was a common site for occult disease. The role of more extensive parietal peritoneal resection for recurrent disease should be evaluated prospectively.

Abstract
BACKGROUND The surgical peritoneal cancer index (sPCI) is calculated based on a subjective evaluation of the extent of peritoneal disease during surgery. The pathologic PCI (pPCI) may be a more accurate and objective method for determining the PCI. This study aimed to compare the sPCI and pPCI and to study the potential pitfalls and clinical implications of using the pPCI. METHODS This prospective study (July to December 2018) included all patients undergoing cytoreductive surgery (CRS). The pPCI was calculated for each patient and compared with the sPCI. The impact of potential confounding factors on the difference between pPCI and sPCI was evaluated. RESULTS Among 191 patients undergoing CRS at four centers, the pPCI and sPCI were concordant for 37 patients (19.3%). The pPCI was lower than the sPCI for 125 patients (65.4%) and higher for 29 patients (15.1%). The concordance between the two groups was maximum for gastric cancer (38.8%) and colorectal cancer (27.6%) and least for mesothelioma (6.7%) and rare primary tumors (5.6%) (p = 0.04). The difference was 0 to 3 points for 119 patients (62.3%), 4 to 5 points for 27 patients (14.1%), and more than 5 points for 45 patients (23.5%). The rate of concordance was not influenced by the use of neoadjuvant chemotherapy (NACT) (p = 0.4), but the difference was greater when NACT was used (p = 0.03). CONCLUSIONS The pPCI strongly differs from the sPCI for patients undergoing CRS for peritoneal disease and may provide a more accurate evaluation of the peritoneal disease extent. Further studies are needed to determine its prognostic value compared with sPCI, and consensus guidelines are needed for calculating it.

Abstract
Background Delaying surgery after chemoradiation is one of the strategies for increasing tumor regression in rectal cancer. Tumour regression and PCR are known to have positive impact on survival. Methods It's a retrospective study of 161 patients undergoing surgery after neoadjuvant chemoradiation (NCRT) for locally advanced rectal cancer (LARC). Patients were divided into three categories based on the gap between NCRT and surgery, i.e., <8, 8-12 and >12 weeks. Tumor regression grades (TRG), sphincter preservation, post-operative morbidity-mortality and survival were evaluated. Results Sphincter preservation was significantly less in >12 weeks group compared to the other two groups (P=0.003). Intraoperative blood loss was significantly higher in >12 weeks group compared to 8-12 weeks group (P=0.001).There was no difference in major postoperative morbidity and hospital stay among the groups. There was no significant correlation between delay and TRG (P=0.644). At Median follow up of 49.5 months the projected 3-year overall survival (OS) and disease free survival (DFS) were not significantly different among the 3 groups (OS: 79.5% vs. 83.3% vs. 76.5%; P=0.849 and DFS 50.4% vs. 70.6% vs. 62%; P=0.270 respectively). Conclusions Delaying surgery by more than 12 weeks causes more blood loss but no change in morbidity or hospital stay. Increased time interval between radiation and surgery does not improve tumor regression and has no effect on survival.

Abstract
BACKGROUND The aim was to study the patterns of target region (greater omentum, lesser omentum, falciform and umbilical round ligament) involvement in patients undergoing cytoreductive surgery (CRS) from various primary tumors, factors affecting involvement and implications on surgical practice. METHODS All patients undergoing CRS from July 2018 to December 2018 were included in this prospective study. The incidence of target region involvement in presence and absence of visible disease and the impact of primary tumor site, PCI and other variables on target region involvement was evaluated. RESULTS In 191 patients, greater omentum was involved in over 15% of patients irrespective of the primary tumor type and in 15.7% in absence of visible disease. 75% of these had PCI <20. The involvement of the other three target regions was higher than 20% in ovarian cancer, appendiceal tumors and peritoneal mesothelioma. Involvement of these 3 regions was associated with a higher PCI (p < 0.001 for all) and omental involvement (p < 0.001for all). 2.1% of colorectal cancer patients had umbilical round ligament involvement, 4.2% had falciform ligament involvement and none had lesser omentum involvement. CONCLUSIONS Target region involvement varies according to primary tumour site and disease extent. Resection of the greater omentum should be performed during CRS for PM arising from all primary sites. Resection of other target organs may be performed for selected patients with ovarian cancer, peritoneal mesothelioma and mucinous appendiceal tumors in absence of visible disease. For other patients, it should be done only in presence of visible disease.

Abstract
BACKGROUND AND AIM The grade/histological subtype is one of the most important prognostic markers in patients undergoing cytoreductive surgery (CRS). Our aim was to study other potential prognostic information that can be derived from the pathological evaluation of CRS specimens and provide a broad outline for evaluation of these. METHODS This prospective study (July to December 2018) included all patients undergoing cytoreductive surgery (CRS). A protocol for pathological evaluation was laid down which was based on existing practices at the participating centers and included evaluation of the pathological PCI, regional node involvement, response to chemotherapy, morphology of peritoneal metastases (PM) and distribution in the peritoneal cavity. RESULTS In 191 patients undergoing CRS at 4 centers, the pathological and surgical PCI differed in over 75%. Nodes in relation to peritoneal disease were positive in 13.6%. Disease in normal peritoneum adjacent to tumor nodules was seen in >50% patients with ovarian cancer and mucinous apppendiceal tumors. 23.8% of evaluated colorectal PM patients had a complete response and 25.0% ovarian cancer patients had a near complete pathological response to chemotherapy. CONCLUSIONS Pathological evaluation of extent and distribution of peritoneal disease differs from the surgical evaluation in majority of the patients. Lymph node involvement in relation of peritoneal disease is common. The morphological presentation of PM in ovarian cancer and mucinous appendiceal tumors merits evaluation of more extensive resections in these patients. Standardized methods of synoptic reporting of CRS specimens could help capture vital prognostic information that may in future influence how these patients are treated.

Abstract
Our aim was to study the accuracy of CT scan in predicting the peritoneal cancer index (PCI) and the impact of neoadjuvant chemotherapy (NACT), abdominal region, disease volume, and primary tumor site on it. This was a prospective single-center study that included patients undergoing cytoreductive surgery ± HIPEC. The CT-PCI was calculated and compared to the surgical PCI. The accuracy of CT-PCI in predicting the surgical PCI and the difference between the two was evaluated. From January 2018 to August 2018, 50 patients were included. The median CT PCI was 6 (range 0-35) and median surgical PCI was 17 (range 2-35). CT-PCI was more than the surgical PCI in 12 (24%), less in 23 (46%), and same in 15 (30%) with an accuracy of 30%. The highest accuracy was in region 10 and lowest in region 3. It was 15% in patients with ovarian cancer, 30% in PMP, 21% in patients receiving NACT, 35% in high-volume disease, and 42.1% in low volume disease. The CT and surgical PCI varied significantly in patients with ovarian cancer (p < 0.001), following NACT (p = 0.01) and those with moderate volume disease (p < 0.001). CT has a low accuracy in predicting the surgical PCI in both high and low volume disease. The CT-PCI can differ significantly from the surgical PCI in patients with ovarian cancer and in patients who have received NACT for peritoneal disease. The impact of NACT on accuracy of CT-PCI in non-ovarian peritoneal metastases should be evaluated further.

Abstract
Cytoreductive surgery (CRS) and HIPEC results in a median disease-free survival (DFS) of 12-15 months, overall survival (OS) of 23-63 months, and cure in around 15% of patients with colorectal peritoneal metastases (CPM). The wide variation in OS may largely be attributed to different criteria for patient selection employed by different investigators. To evaluate outcomes of CRS and HIPEC for CPM in patients enrolled in the Indian HIPEC registry. A retrospective analysis of patients enrolled in the registry since its inception in March 2016 was performed. The impact of various prognostic factors on DFS and OS was evaluated. From Jan 2013 to Dec 2017, 68 patients underwent CRS with HIPEC at six Indian centers. The median PCI was nine [range 3-35]. Twenty-two (32.3%) had mucinous tumors. A CC-0 resection was performed in 53 (77.9%) and CC-1 in 14 (20.5%). The median DFS was 12 months [95% CI 11.037-12.963 months] and the median OS 25 months [95% CI 18.718-31.282]. The DFS was inferior in patients with right upper quadrant involvement (p = 0.02) and 90-day major morbidity (p = 0.002) and OS inferior in those with 90-day major morbidity (p < 0.001) and mucinous tumors with a PCI > 20. The DFS compares well with results obtained by pioneering teams but we have no "cured" patients. Better patient selection and utilization of systemic therapies could in the future improve the OS. There is a compelling need to identify subgroups of CPM that benefit from the addition of HIPEC to CRS.

Abstract
To explore the relationship of peritoneal, and rectal involvement with lymph nodal metastases to identify clinical parameters to guide systematic nodal dissection in advanced ovarian cancer (stage 3c). It is a retrospective study of stage III C epithelial ovarian cancers undergoing cytoreductive surgery with systematic nodal dissection, from January 2011 to December 2016. LS3 score is a cumulative score given for the presence of size 3 lesion (peritoneal disease measuring more than 5 cm) in regions 5, 6, and 7. The depth of rectal involvement was assigned progressive numerical values from 1 (for serosa) to maximum 4 (for mucosa) to generate rectal involvement score. There were 91 patients. 48.35% patients had LS3 lesions in regions 5, 6, 7. Of these, 36% (27/44) had positive nodes. Of the 41 node-positive cases, 43.9% had single and 34.14% had two station involvements. Rectum was involved in 47 patients (51.64%), serosal involvement being the most common type (50.57%). Twenty patients had positive mesorectal nodes (42.55%). The presence of rectal involvement was influenced by the Peritoneal Carcinomatosis Index (PCI) score, the presence of LS3 in lower quadrants (p = 0.008), and LSE score of lower quadrants (p = 0.003). With the increasing depth of rectal infiltration, mesorectal positivity increased significantly (p = 0.000). In multivariate analysis, lower quadrant (regions 5, 6, 7) PCI, LS3 in lower quadrants, LS3 score, rectal involvement score, and the total number of lines of chemotherapy significantly affected different nodal disease parameters. In advanced ovarian cancer, LS3 disease in regions 5, 6, and 7 and rectal involvement directly impact the nodal metastasis and hence mandates a systematic nodal dissection. Mesorectal nodal involvement significantly increases with the increasing depth of rectal involvement necessitating systematic mesorectal nodal clearance for all rectal resections.

Abstract
HIPEC in addition to interval CRS has shown a survival benefit of 12 months compared to CRS alone. However, there are many controversial issues pertaining to CRS itself which should be addressed first. To compare NACT and primary CRS approaches when CRS is categorized according to the extent of resection. To evaluate the feasibility of performing HIPEC at these two time points. A retrospective analysis of patients with stage III C ovarian cancer undergoing primary and interval CRS + HIPEC was performed. The surgical approach for interval CRS was classified as (1) resection of sites of residual disease alone or (2) resection of sites involved before NACT. The morphological response was divided into different categories, and surgeons had to state what they consider residual disease and what they do not. From January 2013 to December 2017, 54 patients were included (18-primary; 36-interval). Median PCI 11 vs 6.5 (p = 0.07); CC-0 was obtained in 77.7%. Three surgeons resected previously involved sites; three sites of residual disease only. All surgeons resected areas of scarring. Twenty percent patients had residual disease in "normal-looking" peritoneum. Morbidity (p = 0.09), median OS (p = 0.71), and median DFS (p = 0.54) were similar in the two groups. Early recurrence occurred in 50% with resection of residual disease alone compared to 16.6% when previous disease sites were resected (p = 0.07). Interval CRS should be performed to resect sites involved prior to NACT and not just sites of residual disease. HIPEC can be performed in both primary/interval settings with acceptable morbidity.

Abstract
To evaluate the clinical outcomes of patients of pseudomyxoma peritonei of appendiceal origin undergoing cytoreductive surgery and HIPEC. Data collected from members, an independent collaborative group of Indian surgeons specializing in the management of peritoneal surface malignancy (INDEPSO), was analyzed retrospectively. Clinicopathological and perioperative outcomes of patients treated for pseudomyxoma peritonei (PMP) of appendicular origin were evaluated. Ninety-one patients were diagnosed with pseudomyxoma peritonei of appendicular origin between March 2013 and December 2017. The median age was 53 years and 60% were females. The median PCI was 27 [range 3-39] and a CC-0/1 resection was achieved in 83.5% patients. The most common histological grade was low-grade PMP, seen in 71.4% cases. The overall rate of grades 3-4 morbidity was 33% (30/91) and the 90-day mortality rate reported was 6.5%. Pulmonary complications and systemic sepsis emerged as the most significant factors affecting morbidity, mortality, and failure to rescue. At a median follow-up of 24 months, the median OS was not reached and the median PFS was 53 months. On univariate and multivariate analysis, high-grade histology, prior chemotherapy, debulking surgery alone without HIPEC, and high PCI > 10 were predictors of poor progression-free survival. The survival and morbidity results of pseudomyxoma peritonei from appendicular origin following cytoreductive surgery and hyperthermic intraperitoneal chemotherapy are encouraging. With further awareness and understanding of the disease, and improvement in surgical expertise and learning curve, there is scope for further reduction in morbidity and better improvement in survival.

Abstract
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.

Abstract
BACKGROUND The Indian HIPEC registry is a self-funded registry instituted by a group of Indian surgeons for patients with peritoneal metastases (PM) undergoing surgical treatment. This work was performed to • Evaluate outcomes of cytoreductive surgery ± HIPEC in patients enrolled in the registry. • Identify operational problems. METHODS A retrospective analysis of patients enrolled in the registry from March 2016 to September 2017 was performed. An online survey was performed to study the surgeons' attitudes and existing practices pertaining to the registry and identify operational problems. RESULTS During the study period, 332 patients were enrolled in 8 participating centres. The common indication was ovarian cancer for three centres and pseudomyxoma peritonei for three others. The median PCI ranged from 3 to 23. A CC-0/1 resection was obtained in 94.7%. There was no significant difference in the morbidity (p = .25) and mortality (p = .19) rates between different centres. There was a high rate of failure-to-rescue (19.3%) patients with complications and the survival in patients with colorectal PM was inferior. A lack of dedicated personnel for data collection and entry was the main reason for only 10/43 surgeons contributing data. The other problem was the lack of complete electronic medical record systems at all centres. CONCLUSIONS These results validate existing practices and identify country-specific problems that need to be addressed. Despite operational problems, the registry is an invaluable tool for audit and research. It shows the feasibility of fruitful collaboration between surgeons in the absence of any regulatory body or funding for the project.

Abstract
PURPOSE The excision of retroperitoneal germ cell tumor (GCT) is a surgical challenge compounded by the absence of definite surgical guidelines. The aim of this study is to present the surgical difficulties and morbidity associated with resection of these tumors. METHODS Fifteen patients (7 males and 8 females) undergoing excision of retroperitoneal GCT between February 2008 and February 2016 were evaluated. RESULTS Except for an adolescent, the majority of patients were infants (median age: 4months). The surgical excision entailed extensive vascular dissection in all patients with associated significant blood loss in two, adjacent organ removal in five, and vessel repair in one patient. The resection was complete in all except two patients. Both the patients with incomplete resections had immature teratoma and received postoperative chemotherapy. At a median follow-up of 53months, 13 patients are alive and disease free, one patient is alive with stable disease, and one patient had died owing to respiratory complications. There were no local recurrences in the patients with complete excision. CONCLUSION Although the outcomes are excellent after surgery, resection of retroperitoneal GCT is a distinct surgical challenge. The surgical difficulties emanate from the need for extensive vascular dissection and risk to adjacent structures. LEVEL IV EVIDENCE Therapeutic study.
