Chemoradiotherapy or chemotherapy as adjuvant treatment for resected gastric cancer: should we use selection criteria?

BACKGROUND: The management of gastric adenocarcinoma is essentially based on surgery followed by adjuvant treatment. Adjuvant chemotherapy (CT) as well as chemoradiotherapy (CTRT) have proven their effectiveness in survival outcomes compared to surgery alone. However, there is little data comparing the two adjuvant approaches. This study aimed to compare the prognosis and survival outcomes of patients with gastric adenocarcinoma operated and treated by adjuvant radio-chemotherapy or chemotherapy. MATERIALS AND METHODS: We retrospectively evaluated 80 patients with locally advanced gastric cancer (LGC) who received adjuvant treatment. We compared survival outcomes and patterns of recurrence of 53 patients treated by CTRT and those of 27 patients treated by CT. RESULTS: After a median follow-up of 38.48 months, CTRT resulted in a significant improvement of the 5-year PFS (60.9% vs. 36%, p = 0.03) and the 5-year OS (55.9% vs. 33%, p = 0.015) compared to adjuvant CT. The 5-year OS was significantly increased by adjuvant CTRT (p = 0.046) in patients with lymph node metastasis, and particularly those with advanced pN stage (p = 0.0078) and high lymph node ratio (LNR) exceeding 25% (p = 0.012). Also, there was a significant improvement of the PFS of patients classified pN2-N3 (p = 0.022) with a high LNR (p = 0.018). CTRT was also associated with improved OS and PFS in patients with lymphovascular and perineural invasion (LVI and PNI) compared to chemotherapy. CONCLUSION: There is a particular survival benefit of adding radiotherapy to chemotherapy in patients with selected criteria such as lymph node involvement, high LNR LVI, and PNI.

Borderline tumors of the ovary.

BACKGROUND: Borderline tumors of the ovary (BOT) were described for the first time by Taylor in 1929. These lesions have a more favorable outcome than do other ovarian cancers. Their prognosis and treatment are still subject of discussion since they occurred more often in young women where the sparing fertility surgery is always considered primarily. AIM: Evaluate the management of patients with borderline ovarian tumors. METHODS: A retrospective study was conducted in 40 patients with borderline ovarian tumors treated between January 1, 1991 and December 31, 2004. RESULTS: Median follow-up was 43 months, mean age was 44 years. Initial surgery was conservative in 17 patients and radical in 23 cases. Six patients had residual disease. Serous, mucinous and mixte tumors were observed in 18, 21 and 1 cases respectively. Staging was I, II, III in 26, 5, and 9 cases respectively with two pseudomyxomas. Adjuvant Chemotherapy was given in 3 patients. There was a recurrence in 13 patients and seven died. The 5-year overall survival rate was 78 %. Prognostic factors with an impact on survival rate were age, stage of the disease, histological subtype and residual tumor. Factors with a negative impact on recurrence were age, type of surgery and residual disease. With Cox multivariate analysis, residual tumor is an independent factor for overall survival, on the other hand age and type of surgery were significant for recurrence free survival. CONCLUSION: Careful staging followed by complete and radical surgery is mandatory. Unilateral salpingo-oophorectomy with omentectomy and multiple peritoneal biopsies and washing could be indicated in patients with child bearing age. Radical surgery after pregnancy is advised.

[Cutaneous melanoma: about 200 cases]. / Mélanome cutané: A propos de 200 cas.

AIM: To analyze the clinical and pathological aspects of cutaneous melanoma and to determine the prognostic factors. METHODS: This is a retrospective study about 200 cases of cutaneous melanoma collected in Salah Azaiz Institute over a period of 36 years (1969-2005). RESULTS: The mean age was 55.4 years, with a slight female predominance. The tumour was developed on a pre-existent lesion in 31.5% of cases. The average delay of consultation was 18 months. The mean tumor size was 37 mm (10-180 mm). The ulcero exophytic appearance represented 45% of the cases. The tumor was metastatic in 19.5 % of cases. Hands and feet represented 53% of the tumour localizations. The treatment was curative in 71% of cases and palliative in 13% of cases. The lymph node dissection was performed in 59% of the patients. Histologically, nodular melanoma and Grade V of Clark represented 43.5 and 35% of the cases, respectively. The mean tumoral thickness was 14 mm. Chemotherapy, immunotherapy and radiotherapy were performed in 5.5%, 3.5% and 5.5% of cases respectively. The lymph node recurrences were noted in 43.6% of the patients treated with curative intent. The mean recurrence free survival was 76 months. Tumour size > 2 cm, the localization on the leg, Clark level invasion IV and the involvement of the tumour margin were significant prognostic factors for the recurrence free survival. The prognostic factors for the metastasis free survival were: tumour size, tumour localization, type of resection and finally the lymph node dissection. The 5-year overall survival was 28.5% and was influenced significantly by the tumour size, tumour localization, type of resection, involvement of the tumour margins, Clark grade, tumour thickness and finally the lymph node involvement. CONCLUSION: The dismal prognosis can be improved by early diagnosis and especially the prevention based on the photo protection and surveillance of patients at high risk.

Primary thyroid lymphoma: a case series.

INTRODUCTION: Primary Thyroid Lymphoma (PTL) is defined as lymphoma involving the thyroid gland alone or the thyroid gland and adjacent neck lymph nodes without contiguous spread or distant metastases at the time of diagnosis. Most thyroid lymphomas are B cell lymphomas, and 98% of all PTL cases are non-Hodgkin's lymphoma. It is a rare disease accounting for around 5% of the thyroid neoplasms and 2% of extranodal lymphomas. If properly diagnosed and treated, the prognosis is favorable. CASE PRESENTATION: Five cases (three men and two women) of PTL were diagnosed and treated in our institute between January 2005 and September 2019. These are 5 cases of Caucasian origin. The mean age was 76.2 (range: 63-95 years); one patient had associated hypothyroid. One patient had a medical history of breast cancer; one was hypothyroid, and four were euthyroid at the diagnosis. In 4 of these patients, PTL started with compressive symptoms. No patients underwent fine needle aspiration cytology (FNAC) or biopsy for the diagnostic only. In sonography, two cases showed bilateral nodules with goiter; in the three cases it showed nodules in the lobe and isthmus. Technetium-99m scintigraphy was performed on only two patients. Bone Marrow Biopsy (BMB) showed normal cellularity in 4 cases and only one case showed tumor cells. LDH levels were increased in all cases. The extension was evaluated in all patients with cervical and thoracic CT scans, Bone Marrow Biopsy (BMB), beta-2 microglobulin, and serum lactate dehydrogenase (LDH) levels. Three cases were staged as IE and two cases as IIE. Three patients underwent total thyroidectomy; two of them underwent cervical lymph node dissection. Two patients underwent lobectomy. All were diagnosed with lymphoma postoperatively and all were diffuse large B cell lymphoma (DLBCL). One patient completed treatment with R-CHOP (Rituximab, Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone), and two cases received adjuvant chemo-radiotherapy (30 Gy). Two patients died immediately after surgery. CONCLUSION: PTL is a rare disease whose diagnosis should be considered in cases of rapidly growing goitres. Timely needle biopsy in suspected cases can avoid unnecessary surgery. Systemic treatment is required, depending on the stage of the tumour.

A huge prolapsed cervical leiomyoma: A case report.

INTRODUCTION AND IMPORTANCE: Uterine leiomyoma is the most common pelvic tumor in women. Its cervical location is rare and may extend into the vagina in 2.5 % of cases. Treatment of cervical fibroids includes either myomectomy or hysterectomy, depending on the patient's profile and the tumor's characteristics. These fibroids challenge the surgeon because of their proximity to vital pelvic structures and their likelihood of causing surgical complications. CASE PRESENTATION: A 47-year-old woman presented with abdominopelvic pain and a bulky necrotic mass protruding out of her vagina. CT scan showed a large heterogeneous anterior mass of the cervix measuring 30 cm prolapsed in the vagina. She underwent a total hysterectomy with complete resection of the cervical mass. The histopathological report confirmed the diagnosis of a cervical leiomyoma with no signs of malignancy. CLINICAL DISCUSSION: Three types of cervical leiomyoma are known: interstitial, supra-vaginal, and polypoidal. The last one, observed in our case, is the rarest type. When prolapsed in the vagina, cervical leiomyoma can outgrow its blood supply and become necrotic. Several approaches are available for the management of cervical leiomyomas. The approach choice depends on many factors such as the tumor size and location, its extent, and the desire for fertility. CONCLUSION: This report describes the case of a large gangrenous and prolapsed non-pedunculated cervical leiomyoma which remains a rare and disabling complication of this benign tumor for which hysterectomy remains the treatment of choice.

Fertility-Sparing Surgery in Infiltrative Mucinous Carcinoma of the Ovary.

Introduction: Mucinous ovarian carcinoma is often diagnosed early and can affect young patients. The preservation of the female reproductive organ is one of the critical issues, especially for nulliparous women. This case report aims to reconsider the safe outcome of fertility-sparing surgery for infiltrative type mucinous ovarian carcinoma. Case Presentation: A 28-year-old woman with a right mucinous ovarian carcinoma, infiltrative subtype stage IA was treated by right salpingo-oophorectomy, omentectomy, and lymph nodes staging. A 5-year follow-up showed no signs of relapse, and she completed two full-term natural pregnancies. Conclusion: Conservative surgery is a crucial matter for this patient category. The infiltrative type has a poorer prognosis, but few papers have reported the outcome and the safety of fertility-sparing surgery in this context.

Surgical resection of a massive residual retroperitoneal mass after chemotherapy for a paratesticular rhabdomyosarcoma: a case report.

INTRODUCTION: Paratesticular rhabdomyosarcoma is a rare and aggressive mesenchymal tumor, accounting for only 7% of all rhabdomyosarcomas. It is mainly encountered in children and adolescents. The standard treatment consists of radical orchidectomy with negative surgical margins. However, chemotherapy is recommended to control retroperitoneal micrometastasis. The place of surgery for progressive retroperitoneal lymph node metastases remains controversial. We present a case of paratesticular rhabdomyosarcoma with progressive retroperitoneal lymph node metastases treated with surgery. CASE REPORT: We report a case of a 17-year-old North African male with no particular medical history who presented with a left scrotal mass that had been evolving for several months. Beta-human chorionic gonadotropin, alpha-fetoprotein, and lactate dehydrogenase were normal. Scrotal ultrasonography revealed the presence of a 6 cm heterogeneous hypoechogenic tissular mass with cystic areas adherent to the left scrotal wall, which was thickened in some places and vascularized by color Doppler. It exerted a mass effect on the homolateral testicle, which was of average volume. The thoracic-abdominal-pelvic computed tomography scan showed the presence of suspicious paraaortic lymph nodes. The most voluminous one measured 16 × 23 mm2. A left orchidectomy was performed. The final pathology report revealed an 8 cm paratesticular rhabdomyosarcoma of the embryonic type that displaced the testicle without invading it. Without going beyond it, it infiltrated the epididymis, the rete testis, and the albuginea. The surgical margin at the level of the spermatic cord was free. The patient had adjuvant chemotherapy (ifosfamide, vincristine, and dactinomycin). The patient had a challenging paraaortic lymph node dissection since the mass enlaced the left ureter and renal vessels. On histological examination, the paraaortic lymph nodes were metastatic. CONCLUSION: Rhabdomyosarcoma is an aggressive malignancy with high metastatic potential. Therefore, only an accurate diagnosis and early treatment can ensure better survival. Surgery in expert hands seems to be a good option for progressive retroperitoneal nodes. However, further studies are needed to determine the place of surgery in this setting.

Pure Ductal Carcinoma in Situ in The Male Breast: A Rare Entity.

Pure ductal carcinoma in situ of male breast (DCIS) is extremely rare. Only a few cases have been reported until now. Its treatment is not well established. Prognosis is as good as in women. In this study, we reported 3 cases of pure ductal carcinoma in situ in the male breast. The mean age of DCIS patients was 58.3 years. The main symptom was a breast mass. The median size of the tumor was 25 mm. Two patients had an axillary lymph node. The left side was reached in 2 cases. All of the patients underwent mastectomy. The histopathological assessment showed papillary, cribriform, and comedocarcinoma in situ. There was no evidence of invasive carcinoma. In one case, the DCIS was associated with Paget's disease of the nipple. One patient received hormonotherapy. The time of follow-up ranged between 6 and 117 months. One patient developed an invasive recurrence.

Vulvar Darier-Ferrand dermatofibrosarcoma: unusual localization of a rare tumor.

Dermatofibrosarcoma protuberans (DFSP) is a low-to-intermediate grade sarcoma of dermal origin that rarely presents in the vulva, typically occurring on the trunk of young to middle-aged adults. Even though it has a low potential for distant metastases, it often recurs locally. Therefore, surgical excision is the treatment of choice. We report a case of DFSP with fibrosarcoma transformation involving the vulva treated by large excision with tumor free margins followed by plastic reconstruction. Our aim is to highlight this rare disease and through literature evaluate the safety and efficacy of surgical treatment. Early recognition of this rare entity whose localization and the aggressive nature of the fibrosarcomatous component will be an issue in the surgical management.

Dermatofibrosarcoma Protuberans of the Breast in Man: An Extremely Rare Entity With a Review of the Literature.

Dermatofibrosarcoma protuberans (DFSP) is a rare sarcoma of soft tissue representing about 1% of all tumors. In addition, DFSP occurs commonly on the trunk and extremities, and only a few cases of DFSP have been observed on the breast. In men, only 11 cases, including this case, have been reported. In this article, we present a case of left breast DFSP that occurred in a 44-year-old man. The physical examination revealed a left breast tender mass, which invaded the skin. The tumor was staged as T4b N0 M0. Mammography and sonography showed a suspect mass of the left breast. The biopsy and immunochemistry permitted the diagnosis of DFSP of the left breast. The patient had a left mammectomy, with free margins. He presents no evident sign of recurrence 7 months later.

A Single Liver Metastasis From Adenoid Cystic Carcinoma of the Parotid Gland: Case Report.

Adenoid cystic carcinoma is an uncommon malignant neoplasm of the salivary gland. Liver metastasis from salivary gland cancer is a rare situation. In this article, we report the case of a 29-year-old woman treated 5 years previously for adenoid cystic carcinoma of the parotid gland by surgery and radiotherapy, who presented for a large hypervascularized hepatic metastasis of 20 cm. After 3-cycle chemotherapy stability, hepatic surgery was successfully performed. The patient maintained disease-free period of 12 months after the surgical treatment. This rare case represents a therapeutic challenge for oncologists and surgeons. Through this case and a review of the literature, we try to better detail the management of this uncommon entity.

Clinicopathological characteristics of synchronous bilateral breast carcinomas. Report of 30 patients.

AIM: The objective of this study is to determine the clinicopathologic characteristics; incidence and prognosis value of synchronous bilateral breast carcinoma (SBBC). METHODS: This is a retrospective study done in Salah Azaiz Institute of Tunis about 30 patients with synchronous bilateral breast carcinomas diagnosed and treated over a 21-years period going from 1977 to 1997. The definition of synchronous breast lesions is the developpement of the contralateral breast cancer within 6 months. RESULTS: Median age was 49 years. The incidence of SBBC was 0.52%. History family was noted in 3% of our population. Mean tumor size was 40 mm (15-145). Breast conserving therapy was done in 16% of cases (9 patients). Five-year overall survival was 40%. Five year survival rates were 72 and 17% for stage II and III, respectively. Main prognostic factors for survival were lymph node involvement (P=0.004) and disease stage (P=0.02). CONCLUSION: Synchronous bilateral breast carcinoma is a rare entity, with a problem of definition concerning the delay of bilaterlisation. Their prognosis is similar to that of unilateral breast carcinoma patients of equal stage. Hence, breast conserving therapy can be used s fely if indicated.

[Epithelioid leiomyosarcoma of the uterine cervix: two cases]. / Lilomyosarcome épithélioïde du col utérin: a propos de deux cas.

BACKGROUND: The epithelioid leiomyosarcoma of the uterine cervix is a rare tumor. Usually, the presenting symptoms are vaginal bleeding and pelvic pain. Surgery is the standard treatment. AIM: To present the characteristic of this rare pathology by mean of two cases handled in the Institute Salah Azaiz. CASES REPORT: Two patients, aged 51 and 42 years, were referred to our institute for vaginal bleeding. Tumors were classified stage II proximal and II distal (FIGO classification modified by Gustave Roussy Institute). The patients had total hysterectomy with pelvic lymph node dissection. Histological exams confirmed the diagnosis of epithelioid leiomyosarcoma of the uterine cervix. Adjuvant external radiotherapy was performed. At 12 and 36 months, the patients are alive with no evidence disease.

Breast carcinoma arising within fibroadenomas. Report of four observations.

BACKGROUND: Fibroadenoma is a frequent benign breast tumor affecting young woman. The incidence of a carcinoma within adenofibromas is estimated at 0.1 to 0.3%. AIM: The purpose of this study was to evaluate the outcome of patients with breast carcinoma arising within adenofibroma and to determine the clinical characteristics and the prognosis of this rare entity. OBSERVATIONS: We retrospectively report on four cases of carcinomas arising in mammary fibroadenomas. The mean age was 41 years (26-53). In two cases, fibroadenomas was complex, containing cysts, adenosis and apocrine metaplasia. The adjacent parenchyma contained fibrocystic dystrophy lesions associated in one case to intralobular neoplasia lesions. The treatment consisted of a conservative treatment in two cases and a mastectomy plus axillary node dissection in the two others. Radiotherapy was indicated in all cases and chemotherapy done in three cases. All patients are alive with a mean follow up of 4.25 years (3-7) without any sign of recurrence. CONCLUSION: Every benign mammary nodule must necessarily be verified surgically to avoid misdiagnosing any carcinomatous area because at this stage its prognosis is better.

[Primary carcinoid tumors of the ovary. Report of three cases]. / Les carcinoïdes primitifs de l'ovaire. A propos de trois cas.

BACKGROUND: Carcinoïdes tumours are a rare type of ovarian tumours which anatomoclinical behaviour differs a little from epithelial type. AIM: Report of three new cases. CASE REPORT: We report 3 observations of ovarian carcinoid tumours in patients aged 50, 23 and 28 years. All our patients were operated in emergency for twisting of appendix in two patients and for acute peritonitis in the third one. Treatment was a one-sided salpingo-oophorectomy. The diagnosis of carcinoid tumour was retained on to the definitive histological exam then the patients were re operated to complete the resection.
