Use of the surgical Apgar score to enhance Veterans Affairs Surgical Quality Improvement Program surgical risk assessment in veterans undergoing major intra-abdominal surgery.

BACKGROUND: We investigated whether the surgical Apgar score (SAS) may enhance the Veterans Affairs Surgical Quality Improvement Program (VASQIP) risk assessment for prediction of early postoperative outcomes. METHODS: We retrospectively evaluated demographics, medical history, procedure, SAS, VASQIP assessment, and postoperative data for patients undergoing major/extensive intra-abdominal surgery at the Manhattan Veterans Affairs between October 2006 and September 2011. End points were overall morbidity and 30-, 60- , and 90-day mortality. Pearson's chi-square, ANOVA, and multivariate regression modeling were employed. RESULTS: Six hundred twenty-nine patients were included. Apgar groups did not differ in age, sex, and race. Low SASs were associated with worse functional status, increased postoperative morbidity, and 30-, 60- , and 90-day mortality rates. SAS did not significantly enhance VASQIP prediction of postoperative outcomes, although a trend was detected. Multivariate analysis confirmed SAS as an independent predictor of morbidity and mortality. CONCLUSIONS: SAS effectively identifies veterans at high risk for poor postoperative outcome. Additional studies are necessary to evaluate the role of SAS in enhancing VASQIP risk prediction.

Does lymph node ratio affect prognosis in gastroesophageal cancer?

BACKGROUND: Increasing evidence suggests that the ratio of number of nodes harboring metastatic cancer to the total number of lymph nodes examined (lymph node ratio, LNR) may affect survival after esophagogastric resection for cancer. We analyzed the impact of LNR in overall survival in patients undergoing esophagogastric resection for cancer. METHODS: Patients who underwent gastroesophageal resection for cancer (1998 to 2008) were categorized into 4 groups according to their LNR: 113 patients had negative nodes (N0), 86 LNR less than .3, 40 LNR .31 to .6, and 47 LNR greater than .6. Study endpoint was overall median survival. RESULTS: Higher LNR was associated (P < .001) with more advanced stage and adverse pathologic features (eg, grading, venous/perineural invasion). Multivariate analysis demonstrated that LNR is an independent predictor of survival. CONCLUSION: In our experience, LNR correlates with adverse pathologic features and is a negative prognostic factor in patients undergoing radical resection for gastroesophageal cancer.

Postoperative intraperitoneal 5-fluoro-2'-deoxyuridine added to chemoradiation in patients curatively resected (R0) for locally advanced gastric and gastroesophageal junction adenocarcinoma.

PURPOSE: Chemoradiation after surgery for locally advanced gastric cancer improves overall and relapse-free survival compared with observation. However, locoregional recurrences remain high. Accordingly, we instituted this pilot/feasibility study, including intraperitoneal 5-fluoro-2'-deoxyuridine (IP FUDR) as part of the treatment. METHODS: Gastric/gastroesophageal junction adenocarcinoma stage Ib-IV (M0) patients who underwent R(0) resection were eligible and had IP catheters inserted at time of surgery. IP FUDR (3 g/dose/day) was given during study days 1-3 and 15-17 before combined 5-fluorouracil, leucovorin, and external beam radiation (45 Gy). Endpoints included toxicity, completion rate, locoregional recurrence, and survival. RESULTS: Twenty-eight patients (22 men) were enrolled from 2002-2006 at two institutions; their median age was 59.5 years. After R(0) resection, a median 22 (range, 8-102) lymph nodes were examined, and 22 patients had positive nodes. AJCC stages were IB (n = 8), II (n = 10), IIIA (n = 5), IIIB (n = 1), and IV (n = 4). Full-dose IP FUDR and chemoradiation treatment was completed in 20 and 25 patients, respectively. At nearly 4-year median follow-up, 11 patients were disease-free, 5 were alive with disease, 7 were dead of disease, and 1 was dead from other cause; 4 have been lost to follow-up. Recurrences were local in one, intra-abdominal in six, distant in two, multiple sites in two, and unknown in one. The median relapse-free survival is 65.3 months, and the median overall survival has not yet been reached. CONCLUSIONS: IP FUDR before chemoradiation after R(0) gastric cancer resection is well tolerated without compromising completion of postoperative adjuvant treatment. Larger randomized trials studying IP FUDR as part of gastric cancer multidisciplinary treatment are needed to prove efficacy in reducing regional recurrence and improving survival.
