- Abstract
Background: Gastric cancer (GC) with peritoneal carcinomatosis (PC) is traditionally considered a terminal stage of the disease. The use of a multimodal treatment, including cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), can benefit these patients. Our goal was to evaluate the morbidity and survival outcomes of these patients., Methods: This is a retrospective, multicenter study from a prospective national database of patients diagnosed with PC secondary to GC treated with CRS and HIPEC from June 2006 to October 2017., Results: Eighty-eight patients from seven specialized Spanish institutions were treated with CRS and HIPEC, with median age of 53 years; 51% were women. Median Peritoneal Cancer Index (PCI) was 6, and complete cytoreduction was achieved in 80 patients (90.9%). HIPEC was administered in 85 cases with 4 different regimens (Cisplatin + Doxorubicin, Mitomycin-C + Cisplatin, Mitomycin-C and Oxaliplatin). Twenty-seven cases (31%) had severe morbidity (grade III-IV) and 3 patients died in the postoperative period (3.4%). Median follow-up was 32 months. Median overall survival (OS) was 21.2 months, with 1-year OS of 79.9% and 3-year OS of 30.9%. Median disease-free survival (DFS) was 11.6 months, with 1-year DFS of 46.1% and 3-year DFS of 21.7%. After multivariate analysis, the extent of peritoneal disease (PCI ≥ 7) was identified as the only independent factor that influenced OS (hazard ratio [HR] 2.37, 95% confidence interval [CI] 1.26-4.46, p = 0.007)., Conclusions: The multimodal treatment, including CRS and HIPEC, for GC with PC can improve the survival results in selected patients (PCI < 7) and in referral centers.

- Abstract
Background: Curettage mastectomy is indicated as a palliative treatment in locally advanced breast cancer. We present our experience with the use of a DIEP flap reconstruction following extensive mastectomy., Methods: We report the case of a patient with very advanced local breast cancer that was subsidiary to aggressive palliative surgery after chemotherapy., Results: It was considered that the closure that could be performed with the latissimus dorsi muscle was unsuitable, therefore a DIEP flap was performed. The patient was discharged uneventfully., Conclusion: The DIEP reconstruction offers great cutaneous extension. It can be a resource in highly selected cases of locally advanced breast cancer in which surgery becomes the main treatment.

- Abstract
Background: Significant tumor downstaging has been achieved in patients with localized gastric adenocarcinoma by preoperative chemoradiotherapy (ChRT) or induction chemotherapy (Ch). However the influence of ChRT and Ch on postoperative outcomes has not yet been clarified, with very few studies examining this issue. We retrospectively analyzed the efficacy in terms of pathological response and early postoperative complications of two protocols of preoperative ChRT and Ch for locally advanced gastric cancer., Methods: Between 2000 and 2008, 72 patients with operable locally advanced gastric cancer (cT3-4/N+) were treated with preoperative treatment: 1-patients receiving induction Ch or 2-neoadjuvant Ch followed by concurrent ChRT. Postoperative histopathological regression and surgical complications were investigated including variables related to patients, surgical variables, preoperative treatment, and tumor., Results: There were no differences in the incidence of complications between the ChRT and Ch groups (30.9% vs. 33.3%). The most frequent complications were nonspecific surgical complications (pneumonia [12.5%] and infection from intravenous catheters [9.7%]). Risk factors for complications were high-body mass index (BMI > 25 kg/m(2) ) and extension of surgery to the pancreas and spleen. A major pathological response was observed in 33.3% of patients, being more frequent in the ChRT group (47.6% vs. 13.3%; χ(2) , P = 0.0024)., Conclusions: Preoperative treatment with Ch or ChRT for locally advanced gastric cancer can be performed safely with an acceptable operative morbidity and low operative mortality rate with careful consideration of the added risk associated with BMI and surgical resection of the pancreas and spleen. Ch and ChRT is feasible and effective in terms of pathological response and R0 resection., (Copyright © 2011 Wiley-Liss, Inc.)

- Abstract
Purpose: Capecitabine is effective against metastatic breast cancer (MBC). We hypothesized that sequential treatment with dose-dense epirubicin/cyclophosphamide (EC) and docetaxel/capecitabine would be active and tolerable in the adjuvant/neoadjuvant setting., Methods: In this prospective phase II clinical trial patients with HER2-negative and node-positive or locally advanced tumors were eligible to receive four cycles of EC (100/600 mg/m2) every 2 weeks with G-CSF on days 3-10, followed by four cycles of docetaxel/capecitabine (75/1,000 mg/m2 b.i.d., days 1-14) every 3 weeks., Results: Fifty-five patients were enrolled with median age of 49, and 80% had hormone receptor-positive disease. The median tumor size was 2.5 cm, with a median of two axillary nodes involved. Seventy-five percent of the first 20 patients had grade 2/3 hand-foot syndrome (HFS). Dose reduction of capecitabine to 800 mg/m2 reduced the grade 2/3 HFS incidence to 31% in the remaining patients. No grade 4/5 toxicities were observed. All 20 patients treated preoperatively responded, with 5 (25%) pathologic complete responses and 3 additional pT0N1 tumors. At a median follow-up of 48 (range 28-60) months, the event-free and overall survival rates are 91 and 98%, respectively., Conclusions: Sequential treatment with dose-dense EC followed by docetaxel/capecitabine, using a lower capecitabine dose than that approved for MBC, has an acceptable toxicity profile and encouraging activity when used as neoadjuvant or adjuvant treatment of breast cancer.

- Abstract
The Peutz-Jeghers syndrome (PJS) is an autosomal dominant hamartomatous poliposis describred in 1921. Hemminki in 1997 described the presence of LKB-1 mutation tumor-suppressor gen.The patients with PJS develop a higher cumulative incidence of gastrointestinal, pancreas and extraintestinal tumors, being occasion of a renew interest on hamartomatous polyposis syndromes regarding the clinical care, cancer surveillance treatment and long term follow-up.We report the case of a 38 years old male, diagnosed of PJS who developed a multiple adenocarcinoma in duodenum and yeyunum. Surgically treated and with a long-term free disease survival of 11 years represents the sixth case reported in the spanish literature of PJS associated with a gastrointestinal tumor.A critical review, molecular alterations and the established criteria of tumor screening and surveillance are reviewed.

- Abstract
Objective: To present the results of a series of laparoscopic middle pancreatectomies with roux-en-Y duct-to-mucosa pancreaticojejunostomy., Summary of Background Data: Middle pancreatectomy makes it possible to preserve pancreatic parenchyma in the resection of lesions that traditionally have been treated by distal splenopancreatectomy or cephalic duodenopancreatectomy. The laparoscopic approach could minimize the invasiveness of the procedure and enhance the benefits of middle pancreatectomy., Methods: From March 2005 to October 2007, 9 consecutive patients with benign or low malignant potential lesions in the pancreatic neck or body underwent surgery. Laparoscopic middle pancreatectomy with a roux-en-Y duct-to-mucosa pancreaticojejunostomy was planned on all of them. In the first 2 patients, the pancreas was transected by endostapler; in the last 7, the staple line was reinforced with absorbable polymer membrane., Results: The intervention was concluded laparoscopically in every case except 1 (laparoscopic-assisted) in which pancreaticojejunostomy was performed by means of minilaparotomy. Mortality was 0% and perioperative morbidity was 33%, (fistula of the cephalic stump in the first 2 patients (22%)). The pancreaticojejunostomy fistula rate was 0%. The median postoperative hospital stay was 5 days (range, 3-41). In the last 7 patients, in which pancreas was transected with staple line reinforcement material there were no stump fistulas; morbidity decreased to 14% and the median hospital stay was 4 days (range, 3-30)., Conclusions: Laparoscopic middle pancreatectomy is feasible and safe. Duct-to-mucosa pancreaticojejunostomy can be performed safely using this approach. The method of pancreatic transection seems to be decisive in the incidence of cephalic stump fistulas.

- Abstract
Adecuate surgical treatment is mandatory in order to achieve cure in patients with breast cancer. Breast surgeons have to choice the best surgical technique over the breast and over the axillary nodes. Two new surgical aproaches have been implemented in the last decade: oncoplastic conservative surgery and sentinel lymph node biopsy. Oncoplastic surgery provides oncologic safety results and good cosmetic outcome. In this paper the technical steps and indications of different oncoplastic techniques in conservative breast surgery are review. Concerning to axillary surgery sentinel lymph node biopsy is the gold standard. However there are several controversial points in sentinel node biopsy referring to indications, identification and histological findings.

- Abstract
Background: This study analysed the value of [(18)F]fluorodeoxyglucose positron emission tomography (FDG-PET) in detecting axillary lymph node involvement in women with breast cancer., Methods: In the first 150 women in this prospective study, axillary lymph node dissection (ALND) was performed regardless of the PET results. In a second group (125 women) FDG-PET was complemented with sentinel lymph node biopsy (SLNB) only in those who did not have pathological axillary uptake., Results: The sensitivity and specificity of FDG-PET in detecting axillary involvement was 84.5 and 98.5 per cent respectively in the whole series of 275 patients, with two false-positive and 22 false-negative results. False-negative results were associated with some intrinsic tumour characteristics. In 21 women, PET revealed pathological uptake, suggesting involvement of the internal mammary lymph node chain. Whole-body PET identified a second synchronous tumour in five asymptomatic patients and haematogenous metastases in two patients., Conclusion: The high positive predictive value of PET (98.4 per cent) suggests that FDG uptake in the axilla could be an indication for full ALND without previous SLNB., (Copyright (c) 2006 British Journal of Surgery Society Ltd.

- Abstract
Laparoscopic surgery has changed the therapeutic approach in the most frequent esophageal diseases. With the excellent results in the control of symptoms and the low associated morbidity, surgical treatment is increasingly indicated in benign esophageal pathology as a superior alternative to a chronic and less efficient medical treatment. For the hiatus hernia and gastroesophageal reflux, Nissen's fundoplication by laparoscopy is the technique of choice. The best results in the treatment of achalasia are obtained with Heller's laparoscopic myotomy. This growing experience includes the resection of tumours of the esophagus combining thoracoscopy and laparoscopy with similar results to those of open surgery.

- Abstract
Aim: The presence of axillary involvement is the most important prognostic factor in breast cancer. This study analysis the value of 18F-FDG PET in the detection of the lymph node status., Methods: This study includes 200 breast cancer patients. The PET scans were obtained after the injection of 370 MBq of 18F-FDG; the breast areas, axillary, supraclavicular and internal mammary lymph node chains were evaluated. In a subgroup of 100 patients the PET-FDG scan was complemented with the study of the sentinel node (SN) in those cases which did not demonstrate pathological lymph node uptake. The standardized uptake value (SUV) was related to the tumour characteristics of size, histological type, axillary status and histological grading., Results: The sensitivity and specificity of PET-FDG in the detection of axillary involvement was 84.1 and 97.8%, respectively. Seventeen false negative cases were obtained, and were associated with low SUV in the mammary tumour. In 15 cases the PET-FDG scans revealed pathological uptake foci that suggested involvement of the internal mammary chain., Conclusions: The PET-FDG avoids routine SN study in those cases presenting axillary uptake, but it must be complemented by sentinel node study in those cases without pathological uptake. The association of PET-FDG and SN improves the sensitivity in the detection of axillary involvement. Its sensitivity and specificity in the analysis of axillary status can be extended to the evaluation of the internal mammary chain.

- Abstract
Background: Experimental models of warm ischemia in liver transplantation have been employed to study the mechanisms and treatment of ischemia reperfusion injury., Methods: We compared a control group without (group A, n = 10) versus two models of warm ischemia of liver transplants in pigs: namely, occlusion of the hepatic artery and portal vein for 30 minutes (group B, n = 23) and extraction of the liver 60 minutes after cardiac arrest (group C, n = 5). Liver function tests, coagulation studies, and liver biopsies were performed during the first 24 hours post-liver transplant., Results: Clamping of the hepatic vasculature in group B produced a significant liver injury compared with the control group: elevation of the ALT and an abnormal 1-hour post-revascularization biopsy similar to that observed in the cardiac arrest group C. The transaminase levels were lower among group A animals (P <.05). But the hepatic synthetic functions as reflected in the protrombin time (PT) were not affected in group B versus group A. The alteration in PT with respect to the initial value was similar among group A and group B animals, which were significantly less than that in group C (P <.05)., Conclusions: Occlusion of the hepatic artery and portal vein, a simple surgical maneuver, causes moderate damage to a liver graft but less alteration of hepatic synthetic function. Clamping of the hepatic vasculture obtains more long-term survivors after OLT than cardiac arrest.

- Abstract
Background: Although curative resection is the treatment of choice for gastric cancer, controversy exists about the adequate extent of lymph node dissection when resection is performed., Methods: We retrospectively assessed 85 patients who underwent a limited lymphadenectomy (D1) and 71 who had an extended lymph node dissection (D2) in a single institution between 1990 and 1998 (median follow-up, 37.3 months). Prognostic factors were assessed by Cox proportional hazard models adjusted for potential confounders., Results: We found no significant difference in the length of hospital stay (median, 12.1 and 13.1 days), overall morbidity (48.2% and 53.5%), or operative mortality (2.3% and 0%) between D1 and D2, respectively. Five-year survival in the D2 group was longer (50.6%) than in the D1 group (41.4%) for tumor stages (tumor-node-metastasis) >I. In multivariate analysis, tumor-node-metastasis stage (hazard ratio for stages >I vs. 0-I, 11.6), the ratio between invaded and removed lymph nodes, the presence of distant metastases, Laurén classification, and the extent of lymphadenectomy (hazard ratio for D1 vs. D2, 2.3; 95% confidence interval, 1.25-4.30) were the only significant prognostic factors., Conclusions: Our experience shows that extended (D2) lymph node dissection improves survival in patients with resected gastric cancer.

- Abstract
Our objective was to evaluate our experience with the Advanced Breast Biopsy Instrumentation system (ABBI) in non-palpable breast lesions in a prospective study from July 1998 to November 2000. The ABBI system was included in a protocol for BIRADS 4 non-palpable, small (<15 mm) breast lesions. Digital radiographs of both specimen and biopsy cavity were obtained to validate the procedure. A total of 255 ABBI biopsies were performed in 254 patients. In 251 cases the lesions were successfully removed (98.4%). Mammographic lesions consisted of 176 cases of microcalcifications (69%), 51 cases of architectural distortions (20%) and 28 cases of nodules (11%). Seventy-two carcinomas were diagnosed (28.2%). Affected margins were found in 41 cases (56.9%). Residual tumour was seen in 31 patients (43%). Seventeen borderline results and 33 benign architectural distortions obviated further procedures. The complication rate in 10 cases was as follows: 3 wound infections; 4 haematomas; and 3 vasovagal reactions. The main utility of the ABBI system is to allow a reliable diagnosis in complex lesions, such as small clusters of microcalcifications and especially architectural distortions. Surgery can be avoided for borderline cases if the lesion is completely removed and free margins are obtained in the pathology study. Therapeutic use is controversial and can be applied only in selected cases.

- Abstract
Background: Operations for large and recurrent abdominal hernias have a high associated recurrence rate, although it is lower when prosthetic material is used. Expanded polytetrafluoroethylene (ePTFE) seems to be the best tolerated prosthetic material in surgery., Methods: A series of 45 ventral hernias repaired using ePTFE for closure or reinforcement of the herniorrhaphy has been evaluated prospectively. Thirty-six were midline incisional hernias and nine were transverse or pararectal ventral hernias. There were 13 recurrent ventral hernias and three defects were operated as an emergency procedure. The patch was sutured to the anterior aponeurosis with a running non-absorbable suture. Some other kind of intra-abdominal procedure was undertaken in 12 cases., Results: ePTFE was well tolerated. Complications occurred in five patients. Major complications were found in three patients: cutaneous necrosis requiring a myocutaneous flap; and infection of the prosthesis (primary, and secondary to enterocutaneous fistula due to diverticulitis, both requiring removal of the patch). Mean follow-up was 39 months and hernia recurrence occurred in only one patient., Conclusion: This clinical experience shows that ePTFE is a very reliable prosthetic material for the repair of abdominal wall hernias.

- Abstract
The extended lymphadenectomy has been proposed as routine procedure in the surgical treatment of gastric cancer, although some controversies have been published. We present a retrospective analysis on the impact of extended lymph node dissection after total gastrectomy, in terms of post-operative course and histopathologic findings, in a group of 30 patients with R2 lymphadenectomy and in 16 patients with R1 lymphadenectomy. There were no significant differences in duration of operation, amount of blood transfusion and length of hospital stay between the 2 groups. The only significant difference was found in the greater amount of drainage output after R2 lymphadenectomy as compared with R1. There were no mortalities in either group and morbidity rate was similar for both [43% in R1 and 40% in R2) mostly in the form of abdominal infections (18% in R1 and 16% in R2]). A significantly greater number of lymph nodes was identified after R2 gastrectomy. Fifty-three per cent of patients has positive lymph nodes, 12% of them being from the N2 echelon of nodes (including one case of early gastric cancer). Careful lymph node dissection in gastric cancer surgery allows a more precise staging of the tumor with no increase in postoperative morbidity.

- Abstract
En bloc transplantation of the liver, duodenum and pancreas has been successful in humans for the treatment of tumors requiring exenteration of the upper abdomen. We have developed an experimental model in 40 pigs of en bloc transplantation of the liver, duodenum and pancreas. The surgical technique for organ harvesting and preservation has been correct as the early graft function was excellent. We describe in detail the surgical technique in the recipient animal, the anesthetic model and the autopsy findings. Liver function was excellent and endocrine pancreatic function was normal within 8 hours after transplantation. Absorption and insulin-secreting response was normal in a few animals studied with an oral glucose overdose and with the intravenous glucagon test.

- Abstract
We present a retrospective study of 68 esophageal cancer patients treated with surgery between 1975 and 1991. Results showed a resectability of 73.5% with the most frequent surgical approach being a Lewis esophagectomy. The mean hospitalization time was 24.7 days with a postoperative mortality of 7.3%. Other complications included anastomotic leakage, wound infection, sepsis and pulmonary disorders. Over-all survival at 3 years was 17.3%, reaching 24% in resected patients. Survival according to lymph node involvement was 13.4% for lymph node positive patients and 34.5% for node negative patients. According to histopathologic stage, survival rates were 34.6% and 8.59% for early and advanced tumor respectively, the difference being statistically significant using the Mantel-Haenszel test.
