Hot flashes in postmenopausal women treated for breast carcinoma: prevalence, severity, correlates, management, and relation to quality of life.

Research on hot flashes (HFs) after the diagnosis and treatment of breast carcinoma (BC) is scarce. To our knowledge, this research represents the second study of HF prevalence and severity in women with BC and the first study of 1) correlates of HF prevalence and severity, 2) use of HF management strategies, and 3) the relation between HFs and quality of life (QOL) among women with BC.

Prognostic significance of postchemoradiation stage following preoperative chemotherapy and radiation for advanced/recurrent rectal cancers

PURPOSE To evaluate the prognostic significance of postchemoradiation pathologic stage and implications for further therapy following preoperative chemoradiation and surgery for advanced/recurrent rectal cancer. METHODS AND MATERIALS Seventy-seven patients with advanced (fixed or tethered T4) or recurrent rectal cancer were treated with preoperative chemoradation followed by surgical resection of disease. Chemotherapy consisted of either of bolus 5-FU 500 mg/m(2) per day or continuous venous infusion 225 mg/m(2) per day for the duration of radiation. Radiation therapy was planned to be delivered to the whole pelvis to a dose of 45 Gy followed by a boost to the area of the tumor of 5-15 Gy. Total radiation doses ranged from 40 to 63 Gy with a median of 55.8 Gy. Surgical resection was then carried out 6-10 weeks following the completion of treatment (median, 7 weeks). Twenty-eight patients underwent abdominoperineal resection and and 49 patients had sphincter-sparing surgical procedures. None of the patients received postoperative chemotherapy. Follow-up in these patients ranges from 1 year to 8 years with a median of 3 years. RESULTS Significant downstaging of disease was observed with 12/77 (16%) having no residual disease(pT0) and 13% (10/77) found to have pT1-2, N0 disease, 31% (24/77) with pT3-4, N0 and 40% (31/77) for pT0-4, N1-2 cancers. Survival by pathologic stage was 100% for pT0-2, N0 cancers, 80% for pT3-4, N0 and 73% for pTx, N1-2. Local recurrence of disease was observed in 0% of patients with pT0-2, N0 as compared with 13% (3/24) in pT3-4, N0 and 16% (5/31) in pT0-4, N1-2 patients. CONCLUSION Downstaging following preoperative chemoradiation is a significant prognostic factor. Patients with pT0, T1, or T2 disease have an excellent prognosis and are unlikely to fail locally or with systemic disease. However, patient with T3/T4 or N+ disease may benefit from further adjuvant chemotherapy.

PSYCHOSOCIAL ADJUSTMENT AND QUALITY OF LIFE IN WOMEN WITH BREAST CANCER AND BENIGN BREAST PROBLEMS: A CONTROLLED COMPARISON

Comparison of psychosocial adjustment in women with breast cancer (BC) and women with benign breast problems (BBP) has been hampered by a failure to control for age differences between these groups, as well as a failure to assess positive psychosocial adaptation in addition to psychological distress. Age-matched women with breast cancer (n = 80) and benign breast problems (n = 80) completed measures of psychological distress, positive psychosocial adaptation, and general quality of life (QOL). Breast cancer patients had completed primary treatment for breast cancer a mean of 24.6 months prior to participation (range, 6-57 months). Comparison of the BC and BBP groups indicated that the BC group reported (1) poorer physical health and functioning, (2) no differences in psychological distress, and (3) greater positive psychosocial adaptation, such as improved life outlook, enhanced interpersonal relationships, and deeper spiritual and religious satisfaction. Results support the theoretical position that cancer is a transitional event, that is, a traumatic event that alters an individuals assumptive world with the potential to produce long-lasting changes of both a positive as well as negative nature. This underscores the importance of using measures of both psychological distress and positive psychosocial adaptation when assessing psychological adjustment following transitional events such as breast cancer.

Postmastectomy / Postlumpectomy Pain in Breast Cancer Survivors

Few studies have focused on careful assessment of postmastectomy pain (PMP); a chronic neuropathic pain syndrome that can affect women postlumpectomy or postmastectomy for breast cancer (BC). Study aims were to determine the prevalence of PMP in an outpatient sample of breast cancer survivors (BCS), describe subjective and objective characteristics of PMP, and examine the relationship between PMP and quality of life. Breast cancer survivors (n = 134) participated in telephone interviews, and those reporting PMP (n = 36) were invited to a pain center for further evaluation and treatment. Results show PMP is a distinct, chronic, pain syndrome affecting 27% of BCS. Findings support the need for clinical trials evaluating the effectiveness of nonpharmacological or cognitive behavioral therapies in alleviating mild to moderate PMP.

Preoperative chemoradiation in fixed distal rectal cancer: dose time factors for pathological complete response

PURPOSE Preoperative chemoradiation is being utilized extensively in the treatment of rectal cancer. However, a variety of dose time factors in both delivery of chemotherapy and irradiation remain to be established. This study was undertaken to examine the impact of dose time factors on pathological complete response (pCR) rates following preoperative chemoradiation for fixed rectal cancer. METHODS AND MATERIALS Thirty-three patients with fixed rectal cancers were treated with combined 5-fluorouracil (5-FU) chemotherapy and pelvic radiation. Twenty-one patients received bolus 5-FU during the first 3-5 days of radiation and repeated on days 28-33 of their radiation treatment. Twelve patients were treated with continuous infusion (CI) 5-FU, 225 mg/m(2) for the duration of the pelvic radiation. Fifteen patients received a planned total radiation dose of 45 to 50 Gy and 18 patients received a dose of 55 to 60 Gy. Surgical resection was then carried out 6-8 weeks after completion of treatment. RESULTS Diarrhea was the most frequent acute toxicity. Grade 3 diarrhea was observed in 6 patients requiring treatment interruption and was not related to the chemotherapy regimen. There was no Grade 4 or 5 toxicity. pCR was observed in 2 of 21 (10%) patients treated with bolus 5-FU as compared to 8 of 12 (67%) for patients treated with CI (p = 0.002). pCR were observed in 8 of 18 (44%) patients receiving radiation dose > or = 5500 cGy as compared to 2 of 15 (13%) patients treated to a dose < or = 5000 cGy (p = 0.05). In the high-dose radiation (> or = 5500 cGy) group, a significant difference in pCR rate was observed in patients treated with CI, 8 of 12 (67%) (p = 0.017) as compared with bolus 5-FU (0 of 6). There was no significant difference in operative morbidity or in wound healing between patients treated with bolus 5-FU or CI or within the groups treated with low or high doses of radiation. Three patients have developed local recurrence at 14 and 24 months, two in the low-dose group treated with bolus 5-FU and one patient in the CVI group. The overall 5-year survival for the whole group is 71%. CONCLUSION Dose intensity of 5-FU and dose of radiation correlate significantly with the likelihood of achieving a pCR. Continuous infusion 5-FU (CI) and a preoperative radiation dose of 5500 cGy or higher can achieve pCR rates of approximately 50%, even in fixed cancers of the rectum.

Stability and change in posttraumatic stress disorder symptoms following breast cancer treatment: a 1-year follow-up.

While some recent research has examined the prevalence and severity of posttraumatic stress disorder (PTSD)‐like symptoms following cancer treatment, no research has examined temporal change or stability in these symptoms in cancer survivors. Female breast cancer survivors (n=46) participated in an initial telephone interview and a follow‐up interview 12 months later. PTSD symptoms associated with breast cancer were assessed using the PTSD Checklist—Civilian version (PCLC). In general, PTSD symptoms in this population did not diminish over time. While group analyses indicated that PCLC‐total and subscale scores were stable across the two assessments, analyses of PCLC scores indicated that many patients exhibited fairly large (>0.5 S.D.) increases and/or decreases in PCLC‐total or subscale scores. Some evidence suggested that decreases in PCLC scores between the two study assessments were associated with greater social support and experience of fewer traumatic stressors prior to breast cancer diagnosis. Most significantly, the research suggested that women with greater PTSD symptoms at the initial interview were less likely to participate in the follow‐up interview. Implications of this for research and clinical management of PTSD in this population are discussed. Copyright

Reconstruction of the lower lip and chin with the composite radial forearm-palmaris longus free flap

Four cases of total lip and chin reconstruction are presented. In three, the composite radial forearm-palmaris longus free flap was used for reconstruction. In the fourth case, the palmaris longus was separated from the flap but still used as a lower lip sling. In all cases, the entire lower lip and the soft tissue of the chin were reconstructed in one stage. All patients healed primarily, and the three who underwent radiotherapy tolerated it without complications. Lip seal and speech were good, and there was no problem with drooling. Postoperative results emphasize the importance of respecting the aesthetic unit of the lower lip and chin. it involved his entire lower lip and a portion of the chin. In addition, the patient had experienced drooling and difficulty eating or holding cigarettes in his mouth. Physical examination revealed a large ulcerative mass involving the entire lower lip and a hard mass in the submandibular region. The patient was taken to surgery, where a total lower lip and chin resection was performed from commissure to commissure. In addition, a neck dissection was performed. The patient was reconstructed with a left radial artery fasciocutaneous flap with a palmaris longus tendon graft in continuity for lower lip reconstruction. The patient is doing well after 2 years of follow-up.

PHYSICAL SYMPTOMS, DISTRESS, AND BREAST CANCER RISK PERCEPTIONS IN WOMEN WITH BENIGN BREAST PROBLEMS

Physical symptoms, general and breast cancer-specific distress, and perceived breast cancer risk were assessed in 66 women with benign breast problems (BBP) and 66 age-matched healthy comparison (HC) women. BBP women reported significantly greater worry about breast cancer than HC women. Breast symptom incidence and breast cancer risk perceptions were found to mediate group differences in breast cancer worry. Hierarchical regression analyses indicated that perceptions of control over a potential breast cancer prognosis moderate the impact of breast symptoms on reports of breast cancer worry. Implications for risk counseling with BBP women are discussed.

Ultrasound-Guided Fine-Needle Aspiration of Clinically Negative Lymph Nodes Versus Sentinel Node Mapping in Patients at High Risk for Axillary Metastasis

BackgroundSonographically directed fine-needle aspiration is a less invasive and less costly alternative to sentinel node (SN) mapping in breast cancer patients at high risk for metastatic disease but with clinically negative axillae.MethodsRadiographic, cytological, and histological diagnostic data on breast primary tumors from 114 consecutive SN candidates were prospectively assessed for clinicopathologic variables associated with an increased incidence of axillary metastases. Patients in whom these variables were identified underwent sonographic examination of their axillae followed by fine-needle aspiration when abnormal nodes were detected. SN mapping was performed in patients with normal axillary sonogram results or negative cytological results. Patients with positive cytological results proceeded to complete axillary dissection. Final axillary histological outcomes from patients not meeting the high-risk criteria were recorded. Additionally, a cost analysis was performed in which the costs of ultrasonography and ultrasound-guided fine-needle aspiration of the axilla were compared with those of SN mapping.ResultsAccording to our selection criteria, a third of the patients with clinically negative axillae (37 of 114; 32%) were considered at high risk for axillary metastases. Fifty-nine percent of these patients (22 of 37) had metastatic disease on final histological analysis. Forty percent (15 of 37) of high-risk patients were spared SN mapping, with a reduction in health care costs of 20% in this patient population. Eighty-seven percent of patients not meeting high-risk criteria were SN negative.ConclusionsThis study suggests that in patients at increased risk for axillary metastases, the use of sonographic evaluation of the axilla in combination with fine-needle aspiration is not only clinically justified, but also cost-effective.

Distinct lymph nodal sonographic characteristics in breast cancer patients at high risk for axillary metastases correlate with the final axillary stage

The purpose of this study was to assess the clinical relevance, limitations and most common findings of axillary ultrasound and subsequent image-guided aspiration cytology in clinically node-negative breast cancer patients who are at high risk for axillary metastasis. Following institutional review board approval and Health Insurance Portability and Accountability Act (HIPAA) compliance, sonographic axillary surveys from 112 patients considered at high risk for axillary metastases were reviewed retrospectively for the following abnormal features: asymmetric cortical thickening/lobulations; loss or compression of the hyperechoic medullary region; absence of fatty hilum; abnormal lymph node shape; hypoechoic cortex; admixture of normal and abnormal appearing nodes; and increased peripheral blood flow. Patients with either normal or abnormal ultrasound exams, but negative cytology, underwent sentinel node mapping. Patients with abnormal ultrasound and positive cytology proceeded to complete axillary dissection. The number of positive nodes, the size of tumour deposits and the histological pattern of metastatic disease on the positive nodes were then correlated and compared with their corresponding sonographic abnormalities. Abnormalities related to the lymph node cortex were indicative of N1a disease. Features such as loss or compression of the hyperechoic medullary region, absence of fatty hilum, abnormal lymph node shape and increased peripheral blood flow were predictors of N2-3 disease. In conclusion, nodal sonographic characteristics of patients at high risk for metastases are useful predictors of tumour burden in the axilla. When combined with the results from aspiration cytology, these findings could modify the surgical approach to the axilla, eliminating the need for sentinel node mapping in a significant proportion of patients.
