130 Background: Esophageal cancer often presents as locally advanced disease with 15% of patients having T4 tumors upon diagnosis. Esophagectomy was often reserved for palliation given the dismal survival rates and high rates of R1/R2 resections. However, neoadjuvant therapy (NT) has the potential to significantly downstage esophageal cancers and thus increase complete resection rates. We report our experience with surgically resected T4 cancers of the esophagus. Methods: Using a comprehensive esophageal cancer database, we identified patients who underwent an esophagectomy for T4 tumors between 1994 and 2008. Neoadjuvant therapy and pathologic response were recorded and denoted as complete (pCR), partial (pPR), and non-response (NR). Clinical and pathologic data were compared using Fisher's exact and chi-square when appropriate while Kaplan Meier estimates were used for survival analysis. Results: We identified 39 patients with T4 tumors who underwent esophagectomy of which 38 (97%) underwent NT. The median age was 61 (31-79) years with a median follow-up of 32 (5-97) months. There were 3 (7.9%) pCR, 17 (44.7%) pPR, and 18 (47.4%) NR. R0 resections were accomplished in 37 (94.9%). Two patients had incomplete resections. One patient had a R2 resection after NT and was deemed as NR. An additional patient had a R1 resection after NT and was a pPR with a residual 0.2 cm tumor on permanent pathology. There were 14 (35.9%) recurrences with a median time to recurrence of 19.5 (4-71) months. Complete pathologic response represented 1 (7.1%), whereas pPR and NR represented 6 (42.9%), and 7 (50%) respectively of all recurrences. The overall and disease free survival for all patients with T4 tumors was 28% and 34% respectively. Patients achieving a pCR had a 5-year overall and disease free survival of (43% and 47%), compared to pPR (30% and 21%) while there were no 5-year survivors in the NR cohort. Conclusions: T4 esophageal cancer often portends a dismal prognosis even after surgical resection. Historical incomplete resections and dismal survival rates often make surgery palliative rather then curative. However, we have demonstrated that neoadjuvant therapy and down staging of T4 tumors leads to increased R0 resections and improvements in overall and disease free survival.

Abstract   The treatment of esophageal cancer is in constant evolution. Most of the esophageal cancer receive induction chemoradiation therapy. Surgical delay has been studied but the optimal timing has not been clarified. Through the years, surgical delay has been modified by surgeons in our institutions, going from an average of 6 weeks delay to an average of 10 weeks delay. It is time to ask if this change has a real positive impact on our patient. Methods In this retrospective multi-center study, we combined data from two center in Quebec city that performs oncologic esophagectomy. The surgical delay went from 6 to 10 weeks around 2014. All surgeons changed their practice at that moment. We retrospectively analysed 5 years before and after the change of practice and created two cohorts of patients. Our primary outcome compared complete pathologic response rate. Our secondary outcomes were surgical complications, anastomotic leak, disease free survival and overall survival. Results Thirty-eight patients had surgery under 8 weeks (mean: 6 weeks) after their induction chemoradiation compared to 64 patients that had surgery after 8 weeks (mean: 10 weeks). There was no statistical significant difference between groups for the complete pathologic response (32% vs 25%, p = 0,16). Important complications were similar, with a rate of 24% vs 28% (p = 0,69). Anastomotic leaks were less frequent in the less than 8 weeks group, but no statistical significance was obtained (13% vs 27%, p = 0,14).No difference in the disease-free survival rate and overall survival rate was noted (DFS 40% vs 55% (p = 0,32), OS 38% vs 38% (p = 0,29)). Conclusion The treatment of esophageal cancer is in constant evolution, induction therapy and surgical technics involve over time. Surgical delay has no impact on complete pathologic response, complication and overall survival. There is no advantage to wait longer before surgery.

102 Background: The optimal number of lymph nodes harvested remains controversial in patients with esophageal cancer. Pathologic response to neoadjuvant therapy (NT) has demonstrated improved survival. However, little is known regarding the impact of NT or nodal harvest in patients with squamous cell carcinoma (SCC) of the esophagus. We examined the extent of LN harvest and outcome in patients who underwent esophagectomy for SCC. Methods: After IRB approval, using a comprehensive esophageal cancer database we identified patients who underwent esophagectomy between 1994-2011. Clinical and pathologic data were compared using Fisher’s exact and chi-square when appropriate while Kaplan-Meier estimates were utilized for survival analysis. Nodal strata were set at 12 (ST-1), 15 (ST-2), and 20 nodes (ST-3). Pathologic response to NT was defined as complete (pCR), partial (pPR), or non-response (pNR). Results: We identified 76 patients who underwent esophagectomy for SCC between 1994-2011. The median age was 62.5 years (40-85 months) with median follow up of 18.5 months (1-157 months). 48 (63%) were male and 28 (37%) were female. Twenty-eight patients (37%) underwent primary esophagectomy alone (PE) while 48 (63%) patients were treated with NT. Extent of lymphadenectomy had no significant impact on overall survival (OS) or disease free survival (DFS) for the entire cohort ST-1 p=0.8 and p=0.9, ST-2 p=0.5 and p=0.4, and ST-3 p=0.5 and 0.4, respectively. Among the patients who received NT, pCR was observed in 28 (58%), pPR in 14 (29)%, and pNR in 6 (13)%. When examining the degree of pathologic response to treatment, extent of LN harvest had no significant impact on OS or DFS for patients who underwent esophagectomy after NT (p=ns across all strata). Conclusions: The extent of LN harvest failed to demonstrate an overall or disease free survival benefit in patients with squamous cell carcinoma of the esophagus. Moreover, patients treated with NT also did not benefit from increased nodal resection irrespective of their pathologic response.

Background. Cranial nerve involvement at disease presentation of nasopharyngeal carcinoma was not uncommon. We investigated the prognosis of patients with T4-locally advanced NPC, with or without cranial nerve involvement, and compared the outcome of patients treated using different radiotherapy techniques.Methods. In this retrospective study, 83 T4-locally advanced NPC patients were diagnosed according to the seventh edition of the American Joint Committee on Cancer staging system. All patients were treated using three-dimensional conformal radiotherapy (3D-CRT) or intensity-modulated radiation therapy (IMRT). The survival rate was analyzed using the Kaplan-Meier method.Results. The 5-year overall, locoregional-free, and disease-free survival rates of patients treated using IMRT were 88.9%, 75.2%, and 69.2%, respectively. The outcome in these patients was significantly better than that in patients treated using 3D-CRT, with survival rates of 58.2%, 54.4%, and 47.2%, respectively. There was no significant difference in the 5-year overall, locoregional-free, and disease-free survival rates of the patients with (64.2%, 60.5%, and 53.5%, resp.) and without (76.9%, 63.6%, and 57.6%, resp.) cranial nerve involvement.Conclusion. Locally advanced NPC patients treated using IMRT had significantly better outcomes than patients treated using 3D-CRT. Our results showed that the outcome of T4 NPC patients with or without cranial nerve involvement was not different.

Introduction Hypopharyngeal tumors are head and neck malignancies associated with a great mortality rate, and the treatment of advanced lesions constitutes a challenging problem. Pharyngolaryngectomy continues to be the gold standard treatment modality for locally-advanced diseases, and it is currently used as the primary treatment or in cases of relapse after an organ preservation strategy. Objective This study aims to compare the survival rates of patients with advanced hypopharyngeal tumors treated with pharyngolaryngectomy as a primary or salvage option, and identify possible prognostic factors. Methods All patients with advanced hypopharyngeal squamous cell carcinomas who performed pharyngolaryngectomy between 2007 and 2014 were reviewed retrospectively. Results A total of 87 patients fulfilled the aforementioned criteria, and the sample had a mean age of 57.2 years and a male predominance of 43:1. The tumors were located in the pyriform sinus walls (81 tumors), in the posterior pharyngeal wall (4 tumors) and in the postcricoid region (2 tumors). A total of 60 patients underwent surgery as the primary treatment option, and 27 were submitted to salvage pharyngolaryngectomy after a previous treatment with chemoradiotherapy or radiotherapy. The 5-year overall survival was of 25.9%, the 5-year disease-free survival was of 24.2%, and the disease-specific survival was of 29.5%. Conclusion The patients treated with pharyngolaryngectomy as the primary option revealed a better 5-year-disease free survival than the patients who underwent the salvage surgery (35.8% versus 11.7% respectively; p < 0.05). The histopathological criteria of capsular rupture of the lymph nodes (30.1% versus 19.8% respectively for the primary and salvage groups; p < 0.05) and vascular invasion (30.5% versus 22.5% respectively; p < 0.05) reduced the 5-year disease-free survival. Pharyngolaryngectomy as the primary intent revealed a lower local recurrence rate than the salvage surgery (40.6% versus 83.3% respectively; p < 0.05).

Abstract Background Although 18 F- FDG PET/CT is validated in baseline workup of esophageal cancer to detect distant metastases, it remains underused in assessing local staging and biology of the primary tumor. This study aimed to evaluate the association between 18 F- FDG PET/CT-derived parameters of esophageal cancer, and its clinico-pathological features and prognosis.Methods All patients (n=86) with esophageal adenocarcinoma or squamous cell cancer operated between 2005-2014 were analyzed. Linear regression was used to identify clinico-pathologic features of esophageal cancer associated with the tumor’s maximal Standardized Uptake Value (SUV max ), Total Lesion Glycolysis (TLG) and Metabolic Tumor Volume (MTV). ROC curve analysis was performed to precise the optimal cutoff of each variable associated with a locally advanced (cT3/4) status, long-term survival and recurrence. Kaplan Meier curves and Cox regression were used for survival analyses.Results High baseline SUV max was associated with cT3/4 status and middle-third tumor location, TLG with a cT3/4 and cN+ status, whereas MTV only with active smoking. A cT3/4 status was significantly predicted by a SUV max >8.25g/mL (p<0.001), TLG>41.7 (p<0.001) and MTV>10.70 cm 3 (p<0.01) whereas a SUV max > 12.7 g/mL was associated with an early tumor recurrence and a poor disease-free survival (median 13 versus 56 months, p=0.030), particularly in squamous cell cancer.Conclusions Baseline 18 F- FDG PET/CT has a high predictive value of preoperative cT stage, as its parameters SUV max , TLG and MTV can predict a locally advanced tumor with high accuracy. A SUV max > 12.7 g/mL may herald early tumor recurrence and poor disease-free survival.

Abstract Background For patients with mid and distal rectal cancer, robust evidence on long-term outcome and causal treatment effects of transanal total mesorectal excision (TaTME) is lacking. This multicentre retrospective cohort study aimed to assess whether TaTME reduces locoregional recurrence rate compared to laparoscopic total mesorectal excision (LapTME). Methods Consecutive patients with rectal cancer within 12 centimetres from the anal verge and clinical stage II-III were selected from three institutional databases. Outcome after TaTME (Nov 2011 - Feb 2018) was compared to a historical cohort of patients treated with LapTME (Jan 2000 - Feb 2018) using the inverse probability of treatment weights method. The primary endpoint was three-year locoregional recurrence. Results A total of 710 patients were analysed, 344 in the TaTME group and 366 in the LapTME group. At three years, cumulative locoregional recurrence rates were 3.6% (95% CI, 1.1–6.1) in the TaTME group and 9.6% (95% CI, 6.5–12.7) in the LapTME group (HR = 0.4; 95% CI, 0.23–0.69; p = 0.001). Three-year cumulative disease-free survival rates were 74.3% (95% CI, 68.8–79.8) and 68.6% (95% CI, 63.7–73.5) (HR = 0.82; 95% CI, 0.65–1.02; p = 0.078) and three-year overall survival 87.2% (95% CI, 82.7–91.7) and 82.2% (95% CI, 78.0-86.2) (HR = 0.74; 95% CI, 0.53–1.03; p = 0.077), respectively. In patients who underwent sphincter preservation procedures, TaTME was associated with a significantly better disease-free survival (HR = 0.78; 95% CI, 0.62–0.98; p = 0.033). Conclusions These findings suggest that TaTME may improve locoregional recurrence and disease-free survival rates among patients with mid and distal locally advanced rectal cancer.

Purpose Although chemoradiotherapy plus resection is considered standard treatment for operable rectal carcinoma, the optimal time to administer this therapy is not clear. The NSABP R-03 (National Surgical Adjuvant Breast and Bowel Project R-03) trial compared neoadjuvant versus adjuvant chemoradiotherapy in the treatment of locally advanced rectal carcinoma. Patients and Methods Patients with clinical T3 or T4 or node-positive rectal cancer were randomly assigned to preoperative or postoperative chemoradiotherapy. Chemotherapy consisted of fluorouracil and leucovorin with 45 Gy in 25 fractions with a 5.40-Gy boost within the original margins of treatment. In the preoperative group, surgery was performed within 8 weeks after completion of radiotherapy. In the postoperative group, chemotherapy began after recovery from surgery but no later than 4 weeks after surgery. The primary end points were disease-free survival (DFS) and overall survival (OS). Results From August 1993 to June 1999, 267 patients were randomly assigned to NSABP R-03. The intended sample size was 900 patients. Excluding 11 ineligible and two eligible patients without follow-up data, the analysis used data on 123 patients randomly assigned to preoperative and 131 to postoperative chemoradiotherapy. Surviving patients were observed for a median of 8.4 years. The 5-year DFS for preoperative patients was 64.7% v 53.4% for postoperative patients (P = .011). The 5-year OS for preoperative patients was 74.5% v 65.6% for postoperative patients (P = .065). A complete pathologic response was achieved in 15% of preoperative patients. No preoperative patient with a complete pathologic response has had a recurrence. Conclusion Preoperative chemoradiotherapy, compared with postoperative chemoradiotherapy, significantly improved DFS and showed a trend toward improved OS.
