Development of breast cancer-related lymphedema: is it dependent on the patient, the tumor or the treating physicians?

INTRODUCTION: Breast cancer-related lymphedema (LE) is relatively common. The aim of this study was to identify the risk factors involved in the development of this complication. METHODOLOGY: This was a cross-sectional study of breast cancer patients treated at our Center between 2004 and 2009. A total of 515 patients were included. Lymphedema was defined as a mid-arm or forearm circumference difference between both limbs of 2 cm or more. RESULTS: The incidence of LE in this population was 21.4 %. Patients with a BMI of 25 or higher had a significantly higher risk of LE (p = 0.002). The presence of lymphovascular invasion (LVI) (p = 0.05) and the number of positive lymph nodes (LN) (p = 0.001) were both associated with LE. Patients who underwent axillary dissection (AD) had a significantly higher incidence of LE than patients who had a sentinel LN biopsy (25 vs. 4.5 %). Adjuvant radiotherapy was also a significant risk factor in patients who had a mastectomy (p = 0.003). CONCLUSION: There are multiple risk factors for LE. Most of those factors can be influenced by early tumor detection. Early tumors are smaller with no LVI or axillary LN metastasis. They do not usually require AD or axillary radiotherapy, which are the strongest factors associated with the development of LE.

Histo-biological comparative analysis of bilateral breast cancer.

Bilateral breast cancer occurs in approximately 7% of surviving breast cancer patients. However, a dilemma exists concerning the notion of whether this represents a de novo second primary tumor versus a breast metastasis. We analyzed 81 patients with bilateral breast cancer, 47 (58%) synchronous tumors and 34 (42%) metachronous tumors. Additionally, charts were reviewed for age, family history, full histology data and biological receptors. We found there were no significant differences in concordance between the first and second primary tumors (in both synchronous and metachronous bilateral breast cancer) with respect to histology; grade; T-category; N-category; ER, PR and HER-2 status. In addition, there was no significant difference in the strength of correlation between ER and PR in the first and secondary primary tumors. Our findings suggest that the differentiation of the origin of contralateral breast cancer based on routine histological and biological concordance is inconclusive. Furthermore, the dilemma will continue to exist until additional molecular approaches are applied routinely for research purposes to resolve the debate.

Lymphedema. A significant health problem for women with breast cancer in Jordan.

OBJECTIVE: To investigate the frequency of breast cancer related lymphedema in our region, and to heighten its awareness among health workers. METHODS: This is a cross-sectional study of patients treated with breast cancer at King Hussein Cancer Center, Amman, Jordan, between January 2004 and December 2009. We excluded patients with bilateral breast cancer. A total of 515 patients were included. We asked the patients to complete questionnaires that included questions related to arm symptoms. Lymphedema was defined as 2 cm or more difference between the 2 upper limbs' girths. RESULTS: The incidence of lymphedema was 21.1%. The subjective evaluation by the patients overestimated the figure (35%). Most patients (75.3%) had limb symptoms, such as pain, numbness, and limitation of movement. In most patients with lymphedema, the symptoms were mild, but in 17 patients (15.6%) the effects were severe. CONCLUSION: Lymphedema continues to be a common health problem in our region. Most patients have mild lymphedema, but in some patients the effects on daily activities are severe. It is important for health workers to understand the significance of this problem and its associated morbidity.

Management strategies for locoregional recurrence in early-stage gastric cancer: retrospective analysis and comprehensive literature review.

OBJECTIVE: To present a comprehensive account and literature review addressing the anatomical distribution, natural history, and management strategies for locoregional recurrence in early-stage gastric cancer (EGC). PATIENTS AND METHODS: Retrospective chart review of patients presenting with EGC recurrence at King Hussein Cancer Center (Amman, Jordan) between July 2006 and May 2009. A literature review of publications addressing recurrence following surgery for EGC was undertaken via a systematic search of PUBMED database and National Comprehensive Cancer Network (NCCN) guideline updates. RESULTS: Seventeen patients presented with EGC, three of whom (17.6%) were pathologically staged as T2N1 [1/33 lymph nodes (LNs)], T1N0, and T1N0 were afflicted by recurrence following R0 partial gastrectomy. Literature review yielded 18 studies specifically addressing recurrence in EGC. Several management strategies have been proposed for isolated recurrence following gastrectomy in EGC. NCCN clinical practice guideline updates do not take into consideration whether the recurrence is isolated or widespread and whether the initial stage is early or advanced. CONCLUSIONS: While acknowledging the limitations of this study, including the small sample size and the short follow-up period, it appears clear that oncologic treatment is possible for EGC recurrence, particularly, in patients with isolated relapse. Guideline updates should differentiate between management strategies suitable for recurrence occurring in early versus advanced initial cancer stage.

Popliteal lymph node dissection for metastatic squamous cell carcinoma: a case report of an uncommon procedure for an uncommon presentation.

Lymph node metastasis from cutaneous squamous cell carcinoma is uncommon. The popliteal fossa is rarely involved with metastasis. Popliteal lymph node dissection is uncommonly performed and not frequently discussed in the literature. We present a case of squamous cell carcinoma of the heel with popliteal and inguinal metastasis. This is followed by a description of the relevant anatomy of the popliteal fossa and the technique of popliteal lymphadenectomy.

A large gastrointestinal stromal tumor of the duodenum: a case report.

INTRODUCTION: Gastrointestinal stromal tumors of the duodenum are uncommon. They can reach a large size. Diagnosis can be elusive and managing them can be difficult. Our case report aims to increase awareness and highlight some issues related to the diagnosis and management of duodenal gastrointestinal stromal tumors. CASE PRESENTATION: We present the case of a 38-year-old Middle Eastern woman with a large, slowly-growing gastrointestinal stromal tumor of the duodenum. Her complaints were minor epigastric discomfort and swelling. A pancreaticoduodenectomy with complete tumor excision was performed. She was doing very well with no evidence of disease recurrence when she was last seen 34 months after her operation. CONCLUSION: Gastrointestinal stromal tumors of the duodenum should be suspected in any patient with a duodenal wall mass. Extramural growth and central ulceration with or without bleeding should alert the endoscopist to the possibility of a duodenal gastrointestinal stromal tumor diagnosis. There is more than one surgical approach available; however, complete surgical excision, with negative margins, is the absolute requirement. Preoperative imatinib mesylate can be considered in unresectable or borderline resectable cases.

Metastasis to the popliteal lymph nodes in lower extremity melanoma and their management.

Melanomas located anywhere below the knee can drain to the popliteal fossa. Sentinel nodes in the popliteal fossa are found in 1-9.6% of cases. The positivity rate in these nodes is 12.5-30%, which is comparable to rates in conventional nodal basins. Formal dissection of the popliteal fossa for a positive sentinel node is indicated. Inguinal dissection based only on the presence of involved popliteal lymph nodes is not warranted.

Ileocaecal intussusception secondary to metastatic phyllodes tumour of the breast.

A patient with phyllodes tumour of the breast is discussed. During follow-up, she presented with intestinal obstruction caused by ileocaecal intussusception. The cause of the intussusception was metastatic phyllodes tumour, which is a unique presentation.

Thymoma and thymic carcinoma arising in a thymolipoma: report of a unique case.

Thymic carcinoma arising within a thymolipoma has not been reported previously. The authors present a unique case of thymoma and undifferentiated thymic carcinoma arising within a thymolipoma in a 36-year-old woman. The bulk of the resected mass was composed of benign fatty tissue admixed with foci of unremarkable thymic tissue; however, it also harbored a central solid mass showing undifferentiated thymic carcinoma associated with a type B2 thymoma. The carcinoma cells were positive for cytokeratin AE1/AE3, cytokeratin 19, and cytokeratin 8/18. They were negative for vimentin, cytokeratin 7, cytokeratin 20, CD5, epithelial membrane antigen, CD30, placental alkaline phosphatase, carcinoembryonic antigen, CD99, leukocyte common antigen, Epstein-Barr virus, inhibin alpha, and protein gene product 9.5. Rare tumor cells showed positive staining for chromogranin and synaptophysin.

Perineal hernia, another incisional hernia?

A secondary perineal hernia is a type of incisional hernia of the pelvic floor, occurring after pelvic surgery such as abdominoperineal excision of the rectum and pelvic exenteration. Our aim is to review the available literature on the subject. This report reviews a recently repaired case, followed by a review of the available literature on the presenting condition, concentrating on approaches and methods of repair. Perineal hernias are uncommon, and not many surgeons face them. It is not known if and how these hernias could be prevented. The method and approach of repair should probably be individualized, but we believe that the use of a mesh is important in the repair of such hernias because of the significant tissue defect prevailing in most of the cases, in addition to the unhealthy tissues related to the use of radiotherapy. The laparoscopic approach has been recently utilized and its use is expected to increase.
