Subcutaneous octreotide versus oral loperamide in the treatment of diarrhea following chemotherapy.

Forty patients with chemotherapy-related diarrhea were randomized to receive (i) octreotide 0.5 mg three times per day s.c. or (ii) loperamide 4 mg three times per day p.o. until complete remission of diarrhea was achieved. In the octreotide group 80% of patients showed complete resolution of loose bowel movements within 4 days of therapy, while in the loperamide group this goal was obtained in only 30% of cases (p < 0.001). If after 4 days no benefit was seen, patients were considered to have failed antidiarrheal therapy. Failure was recorded in only one case (5%) treated with s.c. octreotide and in five patients (25%) who received loperamide. The mean duration of antidiarrheal therapy necessary to achieve remission was 3.4 days in the octreotide group and 6.1 days in the lorepamide group (p < 0.001). Treatment with octreotide was very well tolerated with mild abdominal pain in 15% of cases and pain in the injection site in 15% of patients. Subcutaneous octreotide is highly effective in the management of chemotherapy-related diarrhea in cancer patients.

Secretory breast carcinoma with metastatic sentinel lymph node

BackgroundSecretory mammary carcinoma is a rare breast neoplasia originally described in children but sometimes also found in adults. It presents a more favourable outcome than more common histological types of breast carcinoma; published literature in fact reports only a few cases with axillary lymph node metastases and only four cases with distant metastases.Clinical presentationIn this paper we report a rare case of secretory breast carcinoma with axillary lymph node metastases in a 33-year-old woman. To our knowledge, this is the first case of secretory carcinoma involving biopsy of the sentinel lymph node and investigation of the e-cadherin expression.We found positivity for e-cadherin, which would support the hypothesis that this type of tumour is a variant of the infiltrating ductal carcinoma.ConclusionAfter a careful analysis of reported data, we have come to the conclusion that the treatment of choice for patients with secretory breast carcinoma should be conservative surgery with sentinel lymph node biopsy, followed by accurate follow-up. We are of the opinion that while post-operative radiotherapy is indicated in adult patients who have undergone quadrantectomy, it should not be used in children. Although several cases of secretory carcinoma have been treated with adjuvant chemotherapy, there are still no reliable data regarding the real value of such a choice.

Does the use of fibrin glue prevent seroma formation after axillary lymphadenectomy for breast cancer? A prospective randomized trial in 159 patients.

Seroma formation frequently occurs in patients who have undergone axillary lymphadenectomy. The aim of the study was to evaluate the effect of fibrin glue in the prevention of seroma formation after axillary lymphadenectomy.

LigaSure in total thyroidectomy

PurposeLigaSure is a bipolar diathermy system, which achieves vessel sealing with reduced thermal spread. The device has been used successfully in abdominal operations and because of its features, it has been applied recently in thyroid surgery to minimize the risk of complications such as laryngeal nerve palsy and hypocalcemia, and also to reduce the operating time.MethodsBetween June and December 2005, we performed total thyroidectomy for various disorders in 105 patients. We used the LigaSure diathermy system in 53 patients and traditional hemostatic procedures in the other 52. We evaluated the demographic features, histopathological diagnosis, operating times, and relevant postoperative complications.ResultsThe two study groups had similar demographic and histopathological features. The mean operating time ± SD was not significantly shorter in the LigaSure group than in the traditional group (104 ± 12.7 vs 110 ± 15.6 min). None of the patients in either group suffered hemorrhage, definitive hypocalcemia, or definitive laryngeal nerve palsy. Transient hypocalcemia and transient laryngeal nerve palsy developed in 7.54% and in 1.88%, respectively, of the patients in the LigaSure group, and in 7.69% and 1.92%, respectively, of the patients in the traditional group; these differences were not significant.ConclusionsLigaSure is a safe and effective method of hemostasis control, but it did not reduce the incidence of complications or operating times compared with traditional hemostatic procedures; moreover, the operative costs were higher.

Trans-visceral migration of retained surgical gauze as a cause of intestinal obstruction: a case report.

IntroductionA retained surgical sponge in the abdomen is uncommon although it is likely that this finding is underreported in the medical literature. The intravisceral migration of retained surgical gauze is even rarer, as demonstrated by the very few cases reported.Case presentationThree years after undergoing anterior resection of the rectum, a 75-year-old man presented with symptoms of small bowel obstruction. Plain abdominal radiography and CT showed a radio-opaque marker; a foreign body was suspected, probably a piece of retained surgical gauze. An ileotomy of about 5 cm. was performed to confirm this diagnosis and remove the gauze.ConclusionAlthough rare, retained gauze in the abdomen is a complication of surgery. The authors consider that this event may be more frequent than it appears from reports in the literature, probably because of its medico-legal implications. If all such cases were reported, it would be possible to estimate their exact number, classify the occurrence as a possible surgical complication and thus modify its medico-forensic consequences.

Primary extranodal non-Hodgkin lymphomas of the uterus and the breast: report of three cases

The authors describe one case of a rare primitive non-Hodgkin lymphoma of the uterus, and two cases of primary non-Hodgkin lymphoma of the breast. Histologically, the uterine lymphoma, although clinically confined to the uterus, was a diffuse large cell lymphoma, group G according to the Working formulation for Clinical Usage. The two cases of breast lymphoma were a centrocytic-centroblastic and a lymphoplasmocytoid non-Hodgkin lymphoma, respectively. All cases were initially treated with radical surgery plus radiotherapy, but the first patient showed an early recurrence at distant sites, which required systemic cytotoxic chemotherapy. The patient with uterine non-Hodgkin lymphoma received a very intense regimen--i.e. the ProMACE-Cytabom--because of the unfavourable histology, while the two patients with primary breast non-Hodgkin lymphoma received less aggressive CHOP and CVP chemotherapy. All patients are still alive and free of disease 3 to 6 years after initial diagnosis. These cases stress the systemic nature of non-Hodgkin lymphomas even if apparently localized to a single extranodal organ. Thus, although a definitive therapeutic strategy cannot be drawn from the rare and occasional reports in the medical literature, primary extranodal lymphomas require integrated multimodality therapy with radiotherapy and/or chemotherapy.

A prospective evaluation of the activity of human granulocyte-colony stimulating factor on the prevention of chemotherapy-related neutropenia in patients with advanced carcinoma

After informed consent, 86 patients with advanced cancer undergoing potentially myelosuppressive cytotoxic chemotherapy were randomized to receive placebo or subcutaneous granulocyte-colony stimulating factor (G-CSF) 5 micrograms/Kg/day in order to prevent severe neutropenia and its related morbidity. The incidence of neutropenia (absolute neutrophil count < 1,000/mm3) was significantly reduced in patients receiving G-CSF than in controls (18% versus 42%; P < 0.05). The duration of neutropenia was also shortened by the administration of G-CSF (4.8 versus 8.2 days; P < 0.05). Therapy with G-CSF has also a positive impact on the dose-intensity of employed regimens. Patients treated with G-CSF showed oral fungal disease in 9% of cases, while control patients had a 21% incidence (NS). Patients treated with G-CSF received 91% of the programmed dose-intensity as compared to 71% of control patients (P < 0.05). These data strengthen the clinical usefulness of G-CSF in the prevention of chemotherapy-related neutropenia, infections, and reduction in dose-intensity. Further studies are required to establish if the increase in dose-intensity allowed by G-CSF treatment may positively influence the outcome of cancer patients.

The value of intraoperative frozen section examination of sentinel lymph nodes in surgical management of breast carcinoma

PurposeIn breast cancer staging, the need for intraoperative sentinel lymph node (SLN) evaluation has still not been adequately established. This study investigates the impact of intraoperative frozen section (FS) evaluation of SLN to avoid subsequent axillary lymph node dissection (ALND) in patients with positive SLN.MethodsA retrospective review of 364 breast cancer patients undergoing SLN biopsy with intraoperative FS evaluation of SLN was performed.ResultsSensitivity and accuracy of FS examination of SLN were 76.4% and 94.2%, respectively. The sensitivity was significantly higher in larger tumors (p < 0.01). No significant correlation was found between FS and histologic type. A second intervention was avoided in 83.9% of the patients with positive SLN.ConclusionsIntraoperative FS examination of the SLN is a useful predictor of axillary lymph node status in breast cancer patients. The majority of SLN-positive patients allows for immediate ALND in a one-stage surgical procedure.

Lymphoscintigraphy with peritumoral injection versus lymphoscintigraphy with subdermal periareolar injection of technetium-labeled human albumin to identify sentinel lymph nodes in breast cancer patients

Background Preoperative lymphoscintigraphy is without doubt a valid method for the detection of the sentinel lymph node (SLN). There has been considerable debate regarding the optimal site for the introduction of the tracer; various sites include peritumoral (PT), periareolar (PA), subdermal, and intradermal injection. Purpose To evaluate retrospectively the lymphoscintigraphic identification rate of peritumoral (PT) injection versus subdermal periareolar (PA) injection in the detection of SLNs in breast cancer. Material and Methods Between October 2002 and December 2011, a cohort of 906 consecutive patients with biopsy proven breast cancer underwent 914 SLN biopsy procedures. A total of 339 procedures (Group A) were performed using a PT deep injection of radiotracer while 575 procedures (Group B) adopted a subdermal PA injection of radiotracer towards the upper outer quadrant, regardless of the site of the carcinoma. All the patients underwent synchronous excision of the breast cancer and SLN biopsy. Results SLNs were identified in the lymphoscintigram in 308/339 cases (90.85%) of Group A (PT injection) and in 537/575 cases (93.39%) of Group B (PA injection). Furthermore, in 2/339 patients (0.58%) of Group A, internal mammary lymph nodes were found at lymphoscintigraphy, whereas no internal mammary sentinel nodes were found in the Group B patients. The intraoperative identification rate of axillary SLNs was 99.41% (337 of 339) in the Group A patients and 99.65% (573 of 575) in the Group B patients. There was no significant difference in the two groups between the incidence of the number of SLNs detected and the incidence of identification of positive SLNs. Conclusion PT versus PA injection of radiotracer showed comparable success rates for axillary SLN identification, and can be considered a rapid and reliable method.

Primary schwannoma of the thyroid gland involving the isthmus: report of a case

Primary thyroid schwannomas are extremely rare tumors and there are very few reports of such tumors in the literature. This report presents a rare case of schwannoma involving the isthmus of the thyroid in a 47-year-old male, presenting as a symptomatic predominating cold nodule within a multinodular goiter. The patient underwent total thyroidectomy. The histological examination indicated an Antoni A-type schwannoma. The clinical, radiological and pathological findings of the tumor are discussed, emphasizing the difficulty in reaching a correct preoperative diagnosis. Only 18 cases of primary schwannoma of the thyroid gland have so far been described in the literature and, this is only the second report of thyroid schwannoma localized in the isthmus.
