Abstract

Background: Sentinel lymph node (SLN) biopsy has become the standard of care in malignant melanoma, it is commonly identified by intradermal injection of both radiocolloid tracer and Patent Blue Dye (PBD) around the tumor. This study aims to evaluate the efficacy of PBD in identifying inguinal SLN and also the accuracy of SLN mapping performed by peritumoral injection of PBD without combined radioisotope in malignant melanoma of lower extremity.

Methods: Thirty consecutive patients with primary melanoma of lower exteremity who were referred to Cancer Institute of Tehran University of Medical Science between March 2003 to March 2006 were enrolled in this study. All patients had a preoperative pathologic diagnosis of malignant melanoma, median breslow thickness (range 1-4 mm) and none had clinical or radiologic evidence of nodal involvement or distant metastases.

At surgery PBD was injected around the lesion or scar of excisionl biopsy. Subsequently with a 5cm groin incision SLN Biopsy and complete lymph node dissection was done and all lymph nodes were sent for histopathologic examination. SLN examined by both hematoxylin-eosin and immunohistochemical staining.

Results: SLN identification rate was 100%. No complication directly related to PBD injection was seen. Forty-eight sentinel lymph nodes and 195 non sentinel lymph nodes were harvested. Nineteen SLNS were found to be metastasic in 13 patients (47%). In these patients metastases were found in other inguinal lymph nodes.

In the remaining 17 patients, both the SLN itself and the other removed nodes were negative for the metastatic involvement.

Conclusions: Patent blue dye may be enough to identify superficial inguinal SLN in lower extremity melanoma.

Abstract

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: Detection rate of Ductal Carcinoma Insitu of the breast (DCIS) have increased rapidly over the past decade, which is generally attributed to the widespread use of screening mammography. The aim of this study was to evaluate the prevalence of ductal carcinoma in situ in patients who had been referred to Tehran university medical centers.
Methods: In a retrospective study, medical records of the patients with diagnosis of breast cancer in 3 teaching hospitals of Tehran University of Medical Sciences (Cancer Institute, Sina and Shariati Hospitals between 1994-2003) were reviewed and records with ductal carcinoma in situ were selected and analyzed.
Results: Between 2244 medical records of breast cancer 23 patients had DCIS (1.02%). Mean age was 47.3 years just one patient had been detected by screening mammography and others had clinical symptoms. 48% of patients had mass with mean size of 3.3cm. All had undergone open biopsy (four incisional, 19 excisional). Treatment included 65.2% modified radical mastectomy, 30.4% lumpectomy with axillary dissections and 3.8% lumpectomy alone. Nine patients had radiotherapy after surgery and ten took tamoxifen as hormonal therapy. Two patients (8.6%) in lumpectomy group had recurrence in follow ups. Median follow up time was 84 months.
Conclusion: This study shows that the Prevalence of early stages of breast cancer especially ductal carcinoma in situ is extremely low. (DCIS was 1.02 in comparison with 15-30% in western countries). These findings indicate the need for increasing public information about breast cancer in Iran and improving screening programs of breast cancer.

Abstract

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: Routine oophorectomy in women with colorectal cancer is under debate, the aim of this study is to determine incidence, clinicopathologic features and prognostic factors of ovarian involvement in primary colorectal cancer (CRC) and to clear the role of prophylactic oophorectomy.
Methods: Data from primary CRC women treated between years 1990 and 2004 were retrieved and clinical and pathologic features of those who had undergone oophorectomy during CRC surgery were reviewed.
Results: One hundred eighty cases (mean age 47.5 years) were included. In 120(66.6%), ovaries were preserved and 60(33.3%) cases underwent bilateral oophorectomy in addition to primary CRC resection. Reasons for oophorectomy were prophylactic in 22(36.6%), abnormal morphology in 35(58.3%), and undetermined in 3(5%) cases. There were five metastatic carcinomas, eight primary ovarian tumors and 47 normal ovaries in pathologic evaluation. No complication directly related to oophorectomy was noted. Patients with ovarian metastases had higher stages of tumor. Ovarian metastases were not related to menstrual status, CRC location, size, differentiation, and mucin production, as well as abnormal morphology of ovary. The global prevalence of ovarian metastasis in CRC was 2.7%, and isolated ovarian metastases occurred in less than half of them. Of 120 women that underwent colectomy alone, eight (6.6%) developed ovarian metastasis during two years of follow-up. Only three cased had isolated ovarian metastases. No patient with synchronous or metachronous ovarian metastases from CRC survived five years.
Conclusion: Isolated ovarian metastases from primary CRC occur with a low frequency and this may partially explain the debate regarding prophylactic oophorectomy at the time of curative resection for primary CRC.

Abstract

Background: Metalloproteinase enzymes can lead to the digestion of the extracellular matrix and its compounds and ultimately facilitate the metastasis of cancer cells to other tissues. This study aimed to evaluate the activity of matrix metalloproteinases (MMPs) 1 and 13 in the tissue and plasma samples of the patients with breast cancer and their relationship with clinical features of the disease.
Methods: In this experimental study, twenty-five patients with the diagnosis of non-metastatic luminal A breast cancer in the stage 2 or 3 from the patients referred to the Cancer Institute of Iran, as well as eight healthy subjects which was performed in the Cancer Research Center of Tehran University of Medical Sciences from March 2017 to September 2017, were entered into the study. After obtaining written consent, a few biopsies of breast tumor tissues and 10 cc of the whole blood were collected from all the subjects. Then, the collagen zymography assay was used to evaluate the activity of MMPs 1 and 13.
Results: The results of the present study showed that the activity of MMPs 1 and 13 in the plasma samples was significantly increased in comparison with the healthy group (respectively P=0.0055 and P=0.0263). Unlike the MMP-13, the activity level of the MMP-1 in the tumor and plasma samples was significantly different (P=0.0227). Plasma activity levels of MMP-1 (P=0.0037) and MMP-13 (P=0.0311) were also significantly different in stages 2 and 3 of the disease. Unlike the MMP-13, the activity level of MMP-1 was significantly different in lymph nodes between the tissue and plasma samples (respectively P=0.03 and P=0.015). Moreover, there was no significant difference in the activity level of MMPs 1 and 13 with menopausal and non-menopausal status between the tissue and plasma samples.
Conclusion: The results of the present study showed that plasma concentrations of the MMPs 1 and 13 in comparison with their tissue concentrations could be an appropriate diagnostic tool for breast cancer patients.

Abstract

Background: Breast cancer is the most common cancer in women and its treatment includes various surgeries. Breast-Q is a new patient-reported outcome instrument for breast surgery and it should be validated appropriately for clinical research. This study aimed to develop the Persian version of the Breast-Q and validate the reconstruction module to evaluate the quality of life and satisfaction of Iranian women with a previous history of breast reconstruction.
Methods: This study was descriptive and analytical cross-sectional. The study population consisted of women with a previous history of breast cancer and various breast surgeries referred to the outpatient clinic of Cancer Institute, Imam Khomeini Hospital from September 2017 to October 2019, using convenience sampling. After obtaining permission from the MAPI institute and translating all questionnaires into Persian, the validity, and reliability of the breast reconstruction module were evaluated. To confirm face validity, a questionnaire was given to patients to judge each item. To confirm the content validity of the questionnaire, two qualitative and quantitative methods were used. Content validity ratio (CVR) was calculated based on the expert opinion (Lawshe formula). Waltz & Bausell’s method was used to examine the content validity index (CVI). Finally, a new version of the questionnaire was assessed in 20 women who had undergone TRAM flap breast reconstruction at least 6 months ago.
Results: After translation of the questionnaire into Persian, and face and content validation process, the 116 items of the first questionnaire converted to 72 with an acceptable impact score greater than 1.5 and CVR and CVI. The internal validity of the breast reconstruction module was approved by Cronbach's alpha value of 0.94.
Conclusion: Considering the limitation of the specific questionnaires for various breast surgery procedures, the Breast-Q questionnaire can be an efficient tool for the evaluation of the quality of life and satisfaction in patients. Since the translation of the questionnaire has become valid and reliable, it can be used for future research by other researchers.
