Ampullary cancer in a patient with familial adenomatous polyposis - a rare case report and current status of management

Familial adenomatous polyposis (FAP) is an inherited autosomal dominant disorder. Extracolonic manifestations are seen quite often. As prophylactic colectomy has become a standard care in FAP patients, the concerns over the development of associated extracolonic malignancies have become more prevalent. The authors report a case of a patient with the history of subtotal colectomy because of FAP with the development of adenocarcinoma of papilla of Vater twenty-six years later. A radical procedure in form of proximal pancreaticoduodenectomy was indicated. Variable endoscopic surveillance protocols and treatment strategies have been proposed concerning the management of duodenal and periampullary lesions. In case of periampullary malignancies, the radical surgical resection offers the only chance for cure and the only option that may safeguard the long‑term survival (Fig. 2, Ref. 30). Keywords: ampulla of Vater, bile duct, obstructive jaundice, pancreatoduodenectomy, periampullary tumors.

Recurrence after sentinel lymph node biopsy in cutaneous melanoma: a single-center experience in Slovak patients

The standard approach in the management of cutaneous malignant melanoma is considered to be a complete excision of the primary lesion with an appropriate margin of the normal tissue according to Breslow thickness. Usually sentinel lymph node biopsy (SLNB) can help to determine the nodal status, and thus improve the accuracy of staging of the disease. However, the role of SLNB in melanoma treatment remains controversial. NCCN guidelines strongly support routine performance of therapeutic lymphadenectomy in all melanoma patients with clinically positive nodes without radiographic evidence of distant metastases. Patients with positive SLNB should have had completion lymph node dissection (CLND) for regional disease control. Between 2012 and 2016, 168 consecutive patients underwent surgery for primary cutaneous malignant melanoma at St. Elisabeth Cancer Institute in Bratislava. The indication for SLNB and the procedure was made according to international guidelines. In this retrospective study, a cohort of 78 patients was analyzed (35 women and 43 men). Inclusion criteria comprised patients with cutaneous melanoma with no evidence of distant metastases or clinical lymphadenopathy. SLNB comprised a dual labelling method (Tc-99m Nanocolloid / blue dye) in a one-day protocol. Median follow-up was 657 days. The primary composite outcome was the time to the first disease-related event (death, reintervention, worsening of symptoms). Primary outcome measures were overall (disease-specific) and disease-free survival. The overall identification rate of SLN in melanoma patients by dual labelling method was 98.5%. All patients with positive SLNB on frozen section underwent complete regional lymphadenectomy. Using multivariable analysis Breslow thickness of the lesion (p=0.00004, HR 4.03 on logarithmic scale) was identified as the strongest independent predictor of the disease-free survival (DFS) and male gender was significant predictor of DFS. An increase in tumor thickness was associated with significantly higher risk of an event. Neither SLN positivity nor initial S-100 level proved to be significant predictors of the event at the 0.05 level of probability. Multidisciplinary approach represents the gold standard of care for melanoma patients and surgery remains the best option for most localized cases. Although the usefulness of SLNB procedure has been questioned, it provides an excellent staging method, moreover, it can identify high-risk patients. The routine use of completion lymphadenectomy after a positive SLNB is still controversial. It is not clear whether CLND following a positive SLN biopsy improves survival but it could provide regional disease control.

Surgical management of breast cancer liver metastases

We analyzed the treatment results in patients who underwent hepatic resection for breast cancer liver metastases(BCLM).Between 1/2003 and 12/2012, 15 patients underwent hepatic resection for BCLM. All primary breast tumors were diagnosed as invasive breast cancer. Synchronous BCLM ocurred in 2 patients and 13 patients presented with metachronous BCLM. Median age of patients at the time of BCLM diagnosis was 51 years(range from 31 to 73 years). All resections were considered as R0. From among 15 resections we performed 10 major hepatic resections according to Couinaud classification(≥3 segments) and the rest were minor ones. There was no postoperative mortality within 60 days . All postoperative complications were managed conservatively. Median hospital stay was 10,5 days, ranging from 7-14 days.Standard therapy for patients with BCLM remains systemic chemo- and hormonal therapy. Hepatic resection as a part of multimodal treatment in tertiary HPB centers can offer in a selected group of patients a safe option for improved survival. Keywords: breast cancer, liver metastases, hepatic resection.

Radionavigated detection of sentinel nodes in breast carcinoma--first experiences of our department

INTRODUCTION

Biopsy and histological evaluation of sentinel lymphatic node limits the axillary node dissection only in cases of positive histological finding and decreases the occurrence of postoperative complications related to the axillary node dissection.

METHODS

We used radiotracer SentiScint, Medi-Radiopharma Ltd, Hungary and preoperatively administered blue dye--Blue Patenté V, Guebert, Aulnay-Sous-Bios, France. 11 (18%) patients were subdued to deep peritimorous application of radiotracer, 10 (16.4%) to sub/intradermal application over the lesions and n 40 (65.6%) patients the application was sub/intradermal and periareolar. The patients underwent an operation protocol of corresponding quadrantectomy, radionavigated blue-dye sentinel node biopsy and axillary dissection.

RESULTS AND CONCLUSIONS

From May 2006 to June 2008, we examined 61 patients with breast carcinoma. They underwent radionavigated and blue-dye sentinel node biopsy. We detected 57 (93.4%) sentinel nodes with preoperative scintigraphy, of which only 51 (83.6%) were detected peroperatively and underwent histological evaluation. In six (9.8%) cases, the "frozen cut" histology of the primary lesion had shown a benign lesion; hence no sentinel node biopsy or axillary disection was performed. 12 (19.7%) of 51 histologically evaluated sentinel nodes had metastatic invasion. We retrospectively compared the histological fund in sentinel and axillary nodes in patients with metastatic sentinel nodes. In 6 (16.6%) cases, the sentinel node was positive of metastatic invasion but axillary nodes were histologically negative, in 6 (16.6%) cases the sentinel node and axillary nodes were positive for metastatic invasion. We observed falsely negative findings in 3 (8.3%) patients with negative histological fund in the sentinel node, but positive axillary nodes (Tab. 3, Fig. 2, Ref. 11).
