Consensus statement for treatment protocols in pressurized intraperitoneal aerosol chemotherapy (PIPAC)
Objectives: Safe implementation and thorough evaluation of new treatments require prospective data monitoring and standardization of treatments. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a promising alternative for the treatment of patients with peritoneal disease with an increasing number of suggested drug regimens. The aim was to reach expert consensus on current PIPAC treatment protocols and to define the most important research topics.
Methods: The expert panel included the most active PIPAC centers, organizers of PIPAC courses and principal investigators of prospective studies on PIPAC. A comprehensive literature review served as base for a two-day hybrid consensus meeting which was accompanied by a modified three-round Delphi process. Consensus bar was set at 70% for combined (strong and weak) positive or negative votes according to GRADE. Research questions were prioritized from 0 to 10 (highest importance).
Results: Twenty-two out of 26 invited experts completed the entire consensus process. Consensus was reached for 10/10 final questions. The combination of doxorubicin (2.1 mg/m(2)) and cisplatin (10.5 mg/m(2)) was endorsed by 20/ 22 experts (90.9%). 16/22 (72.7%) supported oxaliplatin at 120 with potential reduction to 90 mg/m(2) (frail patients), and 77.2% suggested PIPAC-Ox in combination with 5-FU. Mitomycin-C and Nab-paclitaxel were favoured as alternative regimens. The most important research questions concerned PIPAC conditions (n=3), standard (n=4) and alternative regimens (n=5) and efficacy of PIPAC treatment (n=2); 8/14 were given a priority of >= 8/10.
Conclusions: The current consensus should help to limit heterogeneity of treatment protocols but underlines the utmost importance of further research
Durvalumab Plus Carboplatin/Paclitaxel Followed by Maintenance Durvalumab With or Without Olaparib as First-Line Treatment for Advanced Endometrial Cancer: The Phase III DUO-E Trial
PURPOSE Immunotherapy and chemotherapy combinations have shown activity in endometrial cancer, with greater benefit in mismatch repair (MMR)-deficient (dMMR) than MMR-proficient (pMMR) disease. Adding a poly(ADP-ribose) polymerase inhibitor may improve outcomes, especially in pMMR disease. METHODS This phase III, global, double-blind, placebo-controlled trial randomly assigned eligible patients with newly diagnosed advanced or recurrent endometrial cancer 1:1:1 to: carboplatin/paclitaxel plus durvalumab placebo followed by placebo maintenance (control arm); carboplatin/paclitaxel plus durvalumab followed by maintenance durvalumab plus olaparib placebo (durvalumab arm); or carboplatin/paclitaxel plus durvalumab followed by maintenance durvalumab plus olaparib (durvalumab + olaparib arm). The primary end points were progression-free survival (PFS) in the durvalumab arm versus control and the durvalumab + olaparib arm versus control. RESULTS Seven hundred eighteen patients were randomly assigned. In the intention-to-treat population, statistically significant PFS benefit was observed in the durvalumab (hazard ratio [HR], 0.71 [95% CI, 0.57 to 0.89]; P = .003) and durvalumab + olaparib arms (HR, 0.55 [95% CI, 0.43 to 0.69]; P < .0001) versus control. Prespecified, exploratory subgroup analyses showed PFS benefit in dMMR (HR [durvalumab v control], 0.42 [95% CI, 0.22 to 0.80]; HR [durvalumab + olaparib v control], 0.41 [95% CI, 0.21 to 0.75]) and pMMR subgroups (HR [durvalumab v control], 0.77 [95% CI, 0.60 to 0.97]; HR [durvalumab + olaparib v control] 0.57; [95% CI, 0.44 to 0.73]); and in PD-L1-positive subgroups (HR [durvalumab v control], 0.63 [95% CI, 0.48 to 0.83]; HR [durvalumab + olaparib v control], 0.42 [95% CI, 0.31 to 0.57]). Interim overall survival results (maturity approximately 28%) were supportive of the primary outcomes (durvalumab v control: HR, 0.77 [95% CI, 0.56 to 1.07]; P = .120; durvalumab + olaparib v control: HR, 0.59 [95% CI, 0.42 to 0.83]; P = .003). The safety profiles of the experimental arms were generally consistent with individual agents. CONCLUSION Carboplatin/paclitaxel plus durvalumab followed by maintenance durvalumab with or without olaparib demonstrated a statistically significant and clinically meaningful PFS benefit in patients with advanced or recurrent endometrial cancer

Radio-guided occult lesion localization for nonpalpable suspicious breast lesions: A novel technique
Background : Breast screening programs and increased self-awareness has
led to increased identification of early breast cancers. Up to 25% of
mammographicaly identified lesions are nonpalpable, which require a
precise technique to localize and excise completely. Radio-guided
occult lesion localization (ROLL) is a technique, which uses hand held
gamma probe to accurately localize and completely excise occult beast
lesions. ROLL can also be combined with sentinel lymph node biopsy
(SLNB) for early breast cancers. This is a minimally invasive approach
with least morbidity and better patient compliance. Materials and
Methods : 25 cases underwent ROLL for nonpalpable breast lesions. 99m
Tc-sulphur colloid was injected into the center of the lesion under
ultrasound guidance preoperatively. No guidewire localization was
performed. Under general anesthesia, surgical excision of the lesion
was carried out using the hand-held gamma probe. Fifteen patients were
diagnosed with early breast cancer with clear margin status. These
patients also underwent SLNB at the same procedure. Results : Fifteen
out of 25 cases were found to harbor invasive breast cancer. The
pathological margins were clear of tumor in all of these patients. The
sentinel node was identified in all cases. In four out of the 15 cases,
sentinel node harbored occult metastases. Conclusion : ROLL is a
useful method for precise, three-dimensional localization of impalpable
breast tumors with results comparable to those achieved by surgery of
palpable lesions. Furthermore, ROLL is feasible in connection with
sentinel node biopsy in the same setting. It is performed as a day-care
procedure with good cosmesis

Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy in Gastric Cancer with Peritoneal Metastasis—Indian Experience
Abstract
Ashwin K.R.
Introduction Peritoneal metastasis secondary to gastric cancer is associated with poor prognosis. Recent studies have shown that cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) may be an efficacious treatment option for an otherwise palliative condition.
Methods A retrospective single institutional study of patents diagnosed with gastric carcinoma and peritoneal metastasis and treated with CRS and HIPEC from February 2015 to December 2019.
Results Sixteen patients with gastric cancer and peritoneal carcinomatosis were treated with CRS and HIPEC. Three patients underwent upfront surgery, and five patients underwent interval surgery. The mean peritoneal cancer index (PCI) was 3.5, and adequate complete cytoreduction (CC) score of 0/1 was achieved in all patients. All patients received HIPEC with mitomycin C. Major surgical complications were in 12.5% of patients. Grade I surgical site infection was present in one patient. Three patients had prolonged gastrointestinal (GI) recovery. The 30-day mortality was zero. Median follow-up time was 39 months. The median progression-free survival (PFS) was 12 months (95% confidence interval [CI] 6.86–17.13). The median overall survival (OS) was 17 months (95% CI 6.36–27.64).
Conclusion Multidisciplinary treatment of perioperative chemotherapy with CRS and HIPEC is a promising treatment option, which may prolong survival in selected patients, and large randomized clinical trials are warranted for it to become standard of care
