Impact of adjuvant radiotherapy on biological and clinical parameters in right-sided breast cancer.

PURPOSE: In patients with right-sided breast cancer (BC) the liver might be partially irradiated during adjuvant radiotherapy (RT). Thus, we performed a prospective observational study to evaluate the dose delivered to the liver, and its potential biological impact. PATIENTS AND METHODS: We enrolled 34 patients with right-sided BC treated with adjuvant RT. The RT schedules were either the Canadian (42.5Gy in 16 fx) or standard fractionated (50Gy in 25 fx) regimen respectively with 9 (26.5%) and 25 (73.5%) patients each, ± a boost of 10-16Gy. Each patient had a complete blood count and liver enzymes analysis, before starting and during the last week of treatment. RESULTS: A significant decrease in white blood cells and thrombocytes counts was observed during RT. We observed a significant correlation between certain hepatic parameters and the volume of the irradiated liver and/or the mean liver dose. A significant correlation between the volume of the right lung and the liver mean dose was found (P=0.008). In the bivariate analysis, a significant correlation between fatigue and the white blood cell count's evolution was observed (P<0.025). CONCLUSION: With the standard RT technique, incidental irradiation of the liver was documented in a large number of patients, and some significant hepatic parameters alterations were observed, without an apparent clinical impact, but this study cannot exclude them. The liver mean dose was correlated with the right lung volume suggesting that deep inspiration breath hold (DIBH) techniques may represent a way to decrease the liver dose. These findings need to be evaluated in further larger studies.

Rare case of remission of a patient with small cell carcinoma of the ovary, hypercalcaemic type (SCCOHT) stage IV: Case report.

INTRODUCTION: Small cell carcinoma of the ovary (SCC) is a very rare (less than 1 % of ovarien neoplasia), highly undifferentiated, aggressive malignancy affecting young women and linked to a poor prognosis. Overall survive rate is very low (about 16 %). SCCOHT has recently been shown to be associated with SMARCA4 gene mutations and shows some genetic similarities to malignant rhabdoid tumors (MRT). PRESENTATION OF CASE: After a reminder of the clinical, histological description of the SCCOHT and concensus about the medical management, we describe the rare case of a 22 years old patient with complete remission after diagnosis of un undifferentiated SCCOHT stage IV treated by conservative surgery and high-doses chemotherapy, 30 months after diagnosis. DISCUSSION: Thus far, no standard therapy exists for SCCOHT. Treatment modalities are surgery, chemotherapy, radiotherapy and autologous stem cell transplant after high-dose chemotherapy. Research for new treatments includes target therapy. CONCLUSION: Autologous stem cell transplant after high-dose adjuvant chemotherapy seems to lead to the best survival rates. Invasiveness of the treatment depends on the stage of the disease, age of the patient and her fertility-sparing desire. An international collaboration will be needed to standardise practices due of the small number of patients.

The Sentinel Lymph Node in Breast Cancer: Problems Posed by Examination During Surgery. A Review of Current Literature and Management.

The presence of tumor cells can be identified in the lymph node when metastasis has occurred from the primary cancer site into the lymph node (1) If the sentinel lymph node ganglion is negative for the presence of tumor cells at the time of histological examination, the other lymph nodes are also negative in 99% of cases. If no tumor cells are identified in the sentinel lymph node ganglion by histological examination, the other lymph nodes are also negative for the presence of tumor cells in 99% of cases. The sentinel lymph node advantageously replaces axillary dissection as a staging method in breast cancer T1 and T2 (2). Approximately 40% of breast cancers metastasize to axillary lymph nodes and metastatic extension depends on disease stage. Sentinel lymph nodes are affected in the following stages: T1a (4.3%), T1b (19.5%), T1c (23.8%), T2 (48.9%), T3 (66.7%).

Paget's Breast Disease: A Case Report and Review of the Literature.

Paget's disease of the breast is a rare cancer. This typical clinical case illustrates the different epidemiological, clinical, histological, therapeutic, and evolving aspects of the disease. We report a case of Paget's disease in a 43-year-old woman who presented eczema of the nipple. Mammography and ultrasounds did reveal a lesion in situ. The patient was scheduled for mastectomy and sentinel node biopsy. She had chosen a radical bilateral surgery. The histological diagnosis was Paget's disease of the breast with a carcinoma in situ. There was no metastasis in either of the sentinel nodes. Paget's disease must be considered with the presence of a persistent eczematous involvement of the nipple, which does not respond to local treatment. Ultrasounds, mammography, and magnetic resonance imaging can allow searching an underlying cancer and guiding the surgical management. There is no evidence at this time that one of the two surgical techniques (conservative or mastectomy) would improve survival. The prognosis depends on the presence of a palpable mass and the invasiveness of the cancer.

Laparoscopic Adnexectomy for Ovarian Torsion during Late Pregnancy: Case Report of a Non-Conservative Treatment and Literature Analysis.

Diagnosis of adnexial torsion is difficult during pregancy (1). The time of decision and laparoscopy is that of the risk of necrosis of the adnexa and, therefore, of the ovarian prognosis. The loss of an ovary can compromise the following fertility. Even if concerns related to laparoscopy in pregnant patients include a limited surgical field, with a risk of uterine injury and negative fetal effects of CO2 insufflation. Evidence base suggests that minimally invasive surgery can be safe and better than laparotomy for management of adnexal masses during late pregnancy with good postoperative and obstetric outcomes. If for most authors laparoscopy appears to become the best approach for ovarian torsion during pregnancy (2), nonetheless, the ideal surgical laparoscopic approach of adnexa in late pregnancy remains controversial. Since there is no technical gold standard to overcome surgical difficulties which could make laparoscopic procedures as real challenge in patients in second and third trimester (3); at least, in case of radical and non-conservative treatment, the risk for a first trimester of pregnancy is to remove the corpus luteum (1).

Verrucous Carcinoma of the Vulva: A Case Report and Review of the Literature.

Verrucous carcinoma of the vulva is a rare lesion (1). Affecting essentially postmenopausal women, this lesion is a distinct and particular entity in vulval carcinoma classification and its scalability is uncertain and unpredictable. Here, we present a case concerning a 48-year-old patient, without follow-up after a condyloma acuminate of the vulva (large left lip). The origin of this case will be discussed in this article. The treatment decided was only surgical. A review of literature shows the rarity of this lesion of the female genital tract.

A Case Report: Pseudoangiomatous Stromal Hyperplasia Tumor Presenting as a Palpable Mass.

We report a case of woman with a palpable lump on her left breast. On mammography, a huge mass located between the inner and the outer inferior breast quadrants of the left breast was found. The ultrasound examination realized later revealed a heterogeneous mass with smooth and lobulated borders. An MRI was also performed, showing an oval mass with heterogeneous areas of enhancement. Finally, a core biopsy under sonographic guidance revealed a pseudoangiomatous stromal hyperplasia of the breast.

Mutation spectrum and prevalence of BRCA1 and BRCA2 genes in patients with familial and early-onset breast/ovarian cancer from Tunisia.

The contribution of BRCA1/BRCA2 mutations to hereditary breast cancer in the Tunisian population has not been accurately estimated. The purpose of our study was to estimate the incidence and spectrum of pathogenic mutations in BRCA1/2 genes in early onset and familial breast/ovarian cancer among Tunisian women. To identify predictive factors for BRCA1/2 mutations, we screened the entire coding sequences and intron/exon boundaries of BRCA1/BRCA2 genes in 48 patients by direct sequencing. Twelve pathogenic mutations were detected (25%); three in BRCA1 (c.211dupA in four families, c.5266dupC in three families and c.1504_1508delTTAAA in one family) and two novel mutations in BRCA2 (c.1313dupT in two families and c.7654dupT in two families). We also identified 23 different polymorphisms and unclassified variants. These results indicate that our population has a spectrum of recurrent BRCA mutations.

Placental site trophoblastic tumor: a case report and review of the literature.

Placental site trophoblastic tumor is rare. They represent a rare form of gestational trophoblastic disease. They occur mainly in women who have a history of miscarriage, termination of pregnancy, or even a normal or pathological ongoing pregnancy. The clinical course is unpredictable. This malignancy has different characteristics from other gestational trophoblastic tumors. Following a clinical case that we encountered and treated, we conducted a literary research and review, focusing primarily on prognostic factors and treatment.

[Radio-histological correlation of microcalcifications of the breast: a Tunisian center experience]. / Corrélation radio-histologique des microcalcifications du sein. Experience d'un centre Tunisien.

PURPOSE: Evaluation of surgical biopsy for mammary microcalcifications, in Tunisian patients according to the American College of Radiology's recommandations (ACR). MATERIAL AND METHODS: [corrected] 100 patients treated in Salah Azaiez Institute from January 2005 to December 2006, who underwent surgical biopsy for breast microcalcifications The diagnosis was based on mammography associated in 60% of the cases, to ultra-sonography. We correlated biopsies results to ACR classification. RESULTS: 123 surgical biopsies are related to ACR 3 lesions in 72 cases (58.5%) ACR 4 in 39 cases (32%) and ACR 5 in 14 case (11.5%). The histological examination showed malignant lesions in 4 cas/72 ACR3 (5.5%), 19/39 ACR4 (48.7%) and 10 among the ACR5 (71.4%). CONCLUSION: Our preliminary study introduces a diagnostic approach of mammary microcalcifications, that are usually infra-clinic lesions, in a general context of breast tumors detected with an average size of more than 3 cm.

[Typical medullary carcinoma of the breast: a retrospective study about 33 cases]. / Carcinome médullaire typique du sein : étude rétrospective à propos de 33 cas.

OBJECTIVE: Typical medullary carcinoma of the breast is a rare histological form of breast carcinoma. It represents less than 5% of all breast cancer. It is known for its favourable prognosis. Considering the rarity of the series we could retrieve, we aimed at underlining the particularities of this pathology. PATIENTS AND METHODS: Retrospective study about 33 cases of typical medullary carcinoma managed at the Salah-Azaïz Institute during a period of six years between 1994 and 1999. RESULTS: The mean age was 47.5 years. The left breast was concerned in about 55% of cases. Mean tumoral size was 46mm. Sixty-one percent of our patients were treated by radical surgery. Seventy-three percent undergo radiotherapy, 57% chemotherapy and 42% hormonotherapy. The five-year free-disease survival was about 85%. DISCUSSION AND CONCLUSION: Typical medullary carcinoma of the breast is a rare histological form of breast carcinoma. Its treatment is similar to the other breast cancers. Our results agree with the different published studies and confirm its favourable prognosis.

[Secondary breast cancer after treatment for Hodgkin's disease. About seven cases]. / Cancer du sein secondaire après traitement pour maladie de Hodgkin. A propos de sept cas.

OBJECTIVE: Therapeutic results of Hodgkin disease (HD) have improved by the use of combined radio-chemotherapy. However, this association can increase the risk of on-term effects including secondary cancers. In a retrospective study, we collected secondary breast cancer (BC) in patients previously treated with chemoradiotherapy for Hodgkin disease at Salah-Azaïz institute of Tunis. PATIENTS AND METHODS: Between 1975 and 2003, seven patients (six women and one man) treated for HD subsequently developed BC. Mean age at diagnosis of HD was 21 years (12-29). The first treatment was combined chemotherapy (MOPP-ABVD) and radiotherapy for all patients. Radiotherapy was delivered with cobalt 60 with large fields. The median dose was 41.3 Gy (2 Gy/fraction in 6 patients and 3.3 Gy in one). RESULTS: The breast tumours occurred after a median delay of 204 months (132-276). According to the TNM classification, we showed two stage T2, one stage T3, two stage T4b and two stage T4d. The mean clinical size was 47 mm (25-80 mm). All patients had infiltrating carcinoma. Axillary node histological involvement was found in 6 cases. All patients were treated by mastectomy and chemotherapy. Only one patient had a locoregional irradiation. Median survival was 26.5 months (12-48). Four patients died and three are still alive at respectively 24, 31 and 144 months. DISCUSSION AND CONCLUSION: According to the previous data, breast cancer represents 6.3 to 9% of all second cancers occurring after HD treatment. We conclude that especially young women and girls treated for HD should be carefully monitored. We suggest that secondary BC be sometimes treated by conservative radiosurgical approach.

[Benign schwannoma of the breast: about two cases]. / Schwannome mammaire bénin: à propos de deux cas.

Schwannoma is a rare nervous tumor developed on schwan cells. Only 22 cases of breast schwannoma have been published since 2005. It usually appears as a breast lump having clinical and radiological characteristics suggestive of kindness. Its diagnosis is histological. Its treatment is surgical. Through two observations and a review of the literature we would try to remind the characteristics of this tumor.

[Mammary tuberculosis: a retrospective study of 65 cases]. / Tuberculose mammaire: étude rétrospective de 65 cas.

OBJECTIVES: Remember the clinical, morphologic and histological particularities of mammary tuberculosis. Discuss clinical and radiological diagnostic problems caused by this localization, as far as breast cancer is concerned. PATIENTS AND METHODS: This is a retrospective study concerning 65 women suffering from mammary tuberculosis, diagnosed at Salah Azaiez Institute between January 1980 and December 2001. RESULTS: In this series, mammary tuberculosis represents 0.2% of the declared tubercular localizations and 0.3% of the mammary pathologies treated at the institute. The mean age of our patients was 36 years (19 to 79). Clinical findings were misleading. In 60% of cases the aspect was of a malignant tumor, in 24.6% of cases of a benign nodule and in 16.4% of cases of an abscess. The mammography concluded to a malignant lesion in 49% of cases. The fine needle aspiration achieved at 8 patients was negative in 6 cases and brought back the caseum in the 2 others. The diagnosis has been made, for all our patients, after histological study when we found typical tuberculosis lesions on pieces of tumorectomy, or biopsy. The diagnosis of tuberculosis was established; all patients had an anti-tuberculosis medical treatment in a department of infectious diseases out of the institute. DISCUSSION AND CONCLUSION: Clinical and radiological features of mammary tuberculosis are very confusing and cause a diagnostic problem with breast cancers. In front of symptoms evoking tuberculosis, biopsies must be done to eliminate an eventual cancer.

[Pelvic pseudotumoral actinomycosis with multisegmental lumbosacral root failure. A case report]. / Actinomycose pelvienne pseudotumorale avec atteinte multiradiculaire lombosacrée. A propos d'un cas.

We report a case of pseudotumoral pelvic actinomycosis with lumbosacral spinal involvement in a 21 year-old woman. The radiological work-up showed a pseudotumoral left ovarian lesion extended to sacral spine, which involved the fifth lumbar vertebra. Diagnosis of actinomycosis was established in histopathological examination of the tubo-ovarian mass under laparotomy. After four months of treatment with ofloxacin and rifampicin evolution was marked by improvement of general health and infection, associated to a progressive recovery of motricity of the lower limbs. Early diagnosis of pelvic actinomycosis may prevent the occurrence of rare but severe neurological complications of this disease.

[Relapse of gigantomastia after mammoplasty. Report of a case and literature review]. / Récidive d'une gigantomastie après mammoplastie. A propos d'un cas et revue de la littérature.

Gigantomastia is a very rare entity of undetermined aetiology that may be due to hormonal imbalance, decreased hormonal catabolism or hypersensitivity of the target organ. It poses the problem of surgical treatment, which can be exceptionally radical of necessity. We report a case of a 32-year-old woman of whom volume and vasculocutaneous complications required a simple bilateral mastectomy to treat a recurrence of gigantomastia occurring some months after a mammoplasty. Most of the cases of gigantomastia found in the literature are associated to the pregnancy or puberty and very rare cases of spontaneous gigantomastia were listed.
