Durvalumab (D) and PET-directed chemoradiation (CRT) after induction FOLFOX for esophageal adenocarcinoma.

226 Background: Based on the positive results of the CALGB 80803 study (J Clin Oncol 2017;35:1 [abstr]), we have added D to induction FOLFOX and pre-op CRT. Methods: Patients (Pts) had TanyN+ or T3-4NanyM0 esophageal and Siewert Type I-III GEJ adenocarcinoma staged by EUS, PET/CT and CT. Pts received mFOLFOX6 ×2 prior to repeat PET/CT. PET responders (PETr) received 5-FU or capecitabine and oxaliplatin with RT to 50.4Gy, while induction PET non-responders (PETnr) received carboplatin/paclitaxel with RT. All Pts received D 1,500 mg q4W ×2 starting 2 wks prior to and during CRT. Esophagectomy was planned 6-8 weeks after CRT. Pts who had R0 resections received adjuvant D 1,500mg q4W ×6. Results: 36 Pts have been enrolled: 25 GEJ, 11 esophageal; 23 N+ and 32 T3/4. 26 of 36 Pts (72%) are PETr. 2 Pts developed metastatic disease after CRT and 9 Pts remain on preop treatment. 25 Pts have had surgery (Table). Pathologic complete response (pCR) was seen in 6 (24%); 5 Pts (20%) had ypT1N0 tumors with 99% response and 2 Pts (8%) had ypT0N1 with 99% response. 20 Pts (80%) had >90% response. 3 Pts had MSI tumors (2 PETr; 1 pCR, 1 T1aN0 99% response, 1 ypT2N0 90% response). Notable grade (gd) 3/4 adverse events (AEs) observed were neutropenia in 8 Pts (22%), diarrhea and vomiting in 2 Pts each (6%). Notable gd 1/2 AEs in ≥20%: anemia (31 Pts), thrombocytopenia (29 Pts), nausea (21 Pts), fatigue (25 Pts), increased AST (20 Pts), constipation and diarrhea (9 Pts), diarrhea (8 Pts). Immune-related AEs noted were gd 2 dermatitis (2 Pts), gd 3 hepatitis and gd 1 hypothyroidism in 1 Pt each. Median length of post-op stay was 8 days, with 12% anastomotic complication rate, including 1 Pt who died of hematemesis 16 days after discharge from 55-day hospitalization. Conclusions: The addition of D to induction FOLFOX and PET-directed CRT is safe and feasible. pCR and near-pCR in ½ of operated Pts is encouraging and compares favorably to the pCR rate of 31% in CALGB 80803 Pts who received induction FOLFOX. The final pCR rate and correlatives for the fully accrued study will be presented. Clinical trial information: NCT02962063. [Table: see text]

Redo Transanal Soave Pull Through with or without Assistance in Hirschsprung Disease: An Experience in 46 Patients

Introduction Transanal Soave pull through (PT) with or without assistance can be performed as a redo procedure for Hirschsprung disease (HD). In this study, we reviewed the indications and clinical outcomes of redo transanal Soave with or without assistance. Materials and Methods A retrospective analysis was performed on patients who underwent redo transanal Soave with or without assistance in our hospital from 2004 to 2016, and did not have rectourethral fistula or rectovaginal fistula. The Krickenbeck classification system was used to evaluate postoperative bowel function. We analyzed the associated factors of the two main indications. Results In this study, 46 patients were included, representing 5.6% of all HD PTs; 42 patients were initially operated elsewhere and 4 at our hospital. Primary PT surgeries included 38 transanal Soave, 2 Rehbein, 1 Martin, and 5 unknown procedures. The indications for redo PT were residual aganglionosis/transition zone PT (RA/TZPT) (27, 58.7%), anastomotic complication (14, 30.4%), and dilated distal segment (5, 10.9%). The median age of these 46 patients at primary and redo PT was 7.0 months (range, 0.4–137 months) and 45.5 months (range, 7–172 months), respectively. All 46 patients underwent redo transanal Soave PT; 43 patients (93.5%) underwent transanal Soave with laparotomy (n = 42) or laparoscopy (n = 1), and another 3 patients underwent transanal Soave PT. Six patients (13%) experienced complications within 30 days after redo surgery. A total of 43 patients were followed up, and the median follow-up period was 100 months (range, 35–180 months). Two patients could not hold back defecation in some inconvenient conditions. Sixteen patients (37.2%) had soiling, and 8 (18.6%) of 16 patients complained frequent soiling occurrence (more than 1/week). Only one patient complained of constipation (grade 1). Patients with anastomotic complication had more early postoperative complication and higher rate of soiling than patients with RA/TZPT, but there was no statistical difference (p = 0.672 and p = 0.105). Conclusion Transanal Soave PT with or without assistance was effective in resolving different problems after initial PT, while soiling was the most common postoperative problem, especially patients with anastomotic complication.

Anastomotic Leaks after Gastrointestinal Operations- A Prospective Cohort Study

Introduction: Anastomotic leak is the release of intestinal contents into the abdomen at the site of surgical stitch line, where two ends of the bowel have been joined for restoration of the gastrointestinal continuity. There are considerable variations in incidence of anastomotic leaks following gastrointestinal operations which have motivated the present study. Aim: To prospectively follow all the patients who underwent gastrointestinal surgeries and look for clinical signs of anastomotic leak in postoperative period. Materials and Methods: Study population comprised of 613 patients who underwent gastrointestinal operation at a Tertiary Care Hospital during the period from September 2011 to September 2013. After taking Institutional Ethical Committee Clearance enrolment in the study was done with written and informed consent. The site of leak, postoperative day of leak was diagnosed and noted based on clinical examination and radiological investigations.It was a prospectively designed descriptive study so no specific tests were applied. Statistical analysis and percentages were calculated using SPSS 16.0 software. Results: Most of the leaks occurred between eighth to ninth postoperative day and most of the obstruction occurred on sixth and seventh postoperative day. Incidence of anastomotic leaks in the study group was 3.26%. Incidence of anastomotic leaks in small bowel anastomosis is 0.489% compared to large bowel leaks reported to be 0.815%. Peritonitis was present in majority of patients presenting with leak. Incidence of obstruction in recto sigmoid anastomosis was 1.957%. Conclusion: The study suggests that as we move distally in Gastrointestinal Tract (GI) the incidence of anastomotic leak increases and it becomes maximum for colorectal surgeries. Anastomotic complication depends on various factors like age, sex, mode of presentation, procedure done, Hb%, dehydration, nutrition, blood sugar, albumin, peritonitis etc.

A New Surgical Techique for Adenoid Cystic Carcinoma Involving Tracheal Carina

Reported is the successful treatment of a 24-year-old male with adenocystic carcinoma involving the tracheal carina, in which the tumor extended along the right main bronchus across the orifice of the right upper lobe. The patient underwent a carinal resection plus right upper lobectomy and reconstruction of the carina, resulting in neither anastomotic complication nor recurrence of disease during 28 months of follow-up.
