Surgical treatment of papillary thyroid carcinoma without lymph nodal involvement

Background. In the treatment of differentiated thyroid cancer (DTC), in absence of enlarged lymph nodes, the role of routine central lymph node dissection (RCLD) remains controversial. The aim of this study is to analyze data resulting from total thyroidectomy (TT) not combined with RCLD in the treatment of DTC. Methods. We retrospectively evaluated the clinical records of 80 patients treated between January 1996 and December 2003 with TT without RCLND, in absence of suspected enlarged lymph nodes at preoperative ultrasonography and intraoperatively during neck exploration. In this series, 75 patients (93.7%) underwent radioiodine (RAI) ablation, followed by Thyroid Stimulating Hormone (TSH) suppression therapy. In case of locoregional lymph nodal recurrence, a central (VI) and ipsilateral (III-IV) selective lymph node dissection was performed. Results. Incidence of permanent hypoparathyroidism (iPTH < 10 pg/ml) and unilateral temporary vocal fold paralysis were respectively 2.55% and 2.55%. Locoregional recurrence, with positive cervical lymph nodes, after a 10.3 ± 4.7 years mean follow-up was observed in 3 patients (3.75%). They were submitted to a central (VI) and ipsilateral (III-IV) selective neck dissection without significant complications. Conclusions. In our series, TT not combined with RCLD was associated to a low locoregional recurrence rate, even if the lack of a control group treated with RCLD does not allow any generalized assumption. RCLD may be indicated in high risk patients, in whom lymph nodal recurrence is more frequent. More prospective randomized studies are needed to better define the role of RCLD and postoperative radioiodine ablation.

Surgical strategy for the treatment of sporadic medullary thyroid carcinoma: our experience

Background. Medullary thyroid carcinoma (MTC) is a rare disease which accounts for approximately 5-9% of all thyroid cancers and originates from the calcitonin-secerning parafollicular C cells. MTC can be divided into two subgroups: sporadic (75%) or inherited (25%). The majority of patients with invasive MTC have metastasis to regional lymph nodes at the time of diagnosis, as evidenced by the frequent finding of persistently elevated calcitonin levels after thyroidectomy and the high rates of recurrence in the cervical lymph nodes reported in retrospective studies. Objectives. The purpose of the study is to review our single institution's experience with MTC since 1998 and to evaluate surgical strategy, patterns of lymph node metastases and calcitonin response to compartment-oriented lymphadenectomy in patients with primary or recurrent sporadic medullary thyroid carcinoma. Methods. A retrospective review of 26 patients treated for MTC at the “Antonio Cardarelli” Hospital referral center, in Naples, between 1998 and 2012. There were 18 female and 8 male patients, median age at presentation was 55 years, and median follow-up for survivors was 5 years. Total thyroidectomy was performed in all 26 patients; central compartment (CC) node dissection (level VI) in 12 (46%) patients; central plus lateral compartment (LC) node dissection (levels II, III, and IV) in 7 (27%) patients. 4 patients (15%) underwent reoperation for loco-regional recurrent/persistent MTC. Results. After a median post-surgical follow-up of 5 years (range 1-10 years), 63 % of patients were living disease-free, 15% were living with disease and/or persistently elevated calcitonin levels after surgery, 11% were deceased due to MTC and 11 % were lost to follow-up. Conclusions. We agree with most authors advocating for a total thyroidectomy and prophylactic central neck dissection in the setting of clinically detected MTC. Lateral neck dissection may be best reserved for patients with positive preoperative imaging. Nevertheless MTC has a high rate of lymph node metastases that are sub optimally detected preoperatively in the central compartment by neck ultrasound or intra-operatively by the surgeon, and reoperation is associated with a higher rate of surgical complications. In our limited experience, patients with thyroid confined nodular pathology, without nodal disease and unknown preoperative diagnosis of MTC, underwent only total thyroidectomy with a good prognosis.

Duodenal carcinoma at ligament of Treitz. Case report and review of the literature

We report a case of adenocarcinoma of the duodenojejunal angle and remark the rarity of this pathology, the difficulty of diagnosis and treatment peculiar to tumours of the duodenum. Thise rare tumour ischaracterized by polymorphic and non specific symptomatology. The possible therapy is surgery. Radio and chemotherapy don't significantly improve survival

Squamous cell carcinoma of the renal pelvis with stones and inferior vena cava infiltration. Case report

We report a rare case of a 50 year old man with renal squamous cell carcinoma (SCC) who first came to our attention with renal colic and fever not responding to antibiotic or analgesic treatment. He had a long history of kidney stones, but had not undergone any imaging in the last 5 years. Physical examination revealed tenderness and a palpable mass in the right flank and lumbar region. A whole body CT scan was performed, revealing an 11 cm mass in the right kidney infiltrating the inferior vena cava. There were areas of calcification within the mass and multiple stones within the renal pelvis. The tumor was considered unsuitable for resection according to radiological and clinical criteria. The mass was biopsied percutaneously under CT guidance and histological examination revealed squamous cell carcinoma of the renal pelvis. The patient was treated with neoadjuvant chemotherapy and embolization of the renal artery. He died one month after diagnosis. To our knowledge this is the second reported case in the world of renal SCC infiltrating the inferior vena cava and with kidney stones.

Liver resection for hemoperitoneum caused by spontaneous rupture of unrecognized hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is an increasingly common form of cancer. Although its spontaneous rupture is rare in Western countries, it constitutes a surgical emergency and is associated with high mortality. There is a lack of consensus as to the best approach and what parameters to use in choosing it. The three main approaches are conservative, endovascular and resection - the treatment of choice for acute abdominal bleeding. We report a case of hemoperitoneum following the spontaneous rupture of an unrecognized HCV-related HCC in a patient with no history of liver disease. The patient was successfully treated by emergency surgery, with resection of two segments of the left liver.

Giant condyloma acuminatum quickly growing. Case report

Background. Giant Condyloma Acuminatum (GCA) is a rare, slow growing, large cauliflower tumor of the penile foreskin and perianal region with benign histologic appearance but high propensity for local invasion and recurrences. GCA is associated with Human Papilloma Virus (HPV) types 6 and 11 and it also has considerable risk of neoplastic transformation into fully invasive squamous cell carcinoma into about 5 years. Objective. Because of the rarity of perianal GCA, to date there is no general agreement on the best method for treatment. We wanted to know if surgical approach only was a good method to treat our case. Case report. A 28 years old man, HIV-negative, with a 4 years history of perianal GCA quickly growing underwent full tickness local excision at least 0,7 cm margin of normal tissue with skin grafting taken from the thighs. Fecal contamination was avoided by diet and loperamide per os. At two years follow-up no recurrence was detected. Conclusion. Surgical approach with full tickness excision and immediate skin-grafting and regular follow-up demonstrated effective to treat GCA and to minimize disease recurrence.
