Sarcoma radiotherapy

Rhabdomyosarcoma (RMS) is the third most common extra-cranial sarcoma occurring in childhood, adolescents, and young adults (AYAs); and is rare in adults. Literature about RMS mainly considers RMS in AYAs, either with that in the children or adults, even though histological, molecular, and clinical characteristics of RMS in AYAs are significantly different from either of the two. Herein, we report a case of prostatic embryonal RMS, in a 17-year-old boy, along with the review of literature of prostatic RMS, with emphasis on AYAs...

Dermatofibrosarcoma protuberans (DFSP) is a rare, locally aggressive soft tissue sarcoma of the skin. DFSP typically presents as an asymptomatic, firm plaque in its earliest stage, gradually enlarging over months to years. This case report delineates a singular instance involving a 66-year-old female patient previously diagnosed with and treated for DFSP. The individual presented with a recurrent history of hospital admissions, manifesting symptoms of loose stools, generalised weakness, and diminished appetite...

INTRODUCTION: Ewing sarcoma (ES) is a malignant and aggressive bony tumor affecting the most common age group of 5-20 years. It constitutes 10%-15% of all bone sarcomas and is the second most common primary malignant bone tumor after osteosarcoma. It usually presents with pain, which is typically constant and progressive in nature. The primary source of pain is due to the instability of the spine to support the weight of the body, the vertebral body's expanding cortices due to the growing mass, compression of nerve roots due to tumour mass, pathologic fractures, spinal cord compression, and invasion of tissue by the tumour mass...

INTRODUCTION: We encountered a unique case of a patient with two distinct tumors coexisting in the same thigh. To the best of our knowledge, this combination of tumors in the same anatomical region has not been previously described in the literature. CASE REPORT: This case report describes a 38-year-old Caucasian male with a painless mass in his right thigh, which was later diagnosed as a hybrid tumor composed of low-grade fibromyxoid sarcoma and sclerosing epithelioid fibrosarcoma, as well as a second tumor, which was diagnosed as a hibernoma...

BACKGROUND: Ewing's sarcoma is a rare malignant entity. Extraosseous Ewing's sarcoma (EES) of the head and neck region is a rare occurrence, and Ewing's sarcoma of the parotid gland is even rarer. To the best of our knowledge, we reported the first case of extraskeletal ES originating from the parotid gland in the Tunisian literature. CASE REPORT: We report a rare case of EES of the parotid gland in a 35-year-old female. She presented with left parotid tumefaction...

Kaposi's sarcoma (KS) is an angiogenic tumor. KS lesions frequently develop in the skin and oral cavity mucosa in the head and neck regions, and pure laryngeal localization is extremely rare. We reported a 64-year-old male patient without HIV, HBV, and HCV positivity presented with a hemangiomatous lesion detected incidentally in the right vocal cord. Biopsy was taken for histopathological and immunohistochemical evaluation. Examination revealed that spindle cells were of vascular origin and expressed HHV-8, a specific marker associated with Kaposi's sarcoma-associated herpesvirus...

BACKGROUND: Treatment options for patients with metastatic sarcoma are limited. The goal of this study was to investigate the effectiveness of temozolomide in pretreated patients with soft tissue sarcoma. METHODS: We recorded the pathological, clinical, and treatment data of the patients with metastatic soft tissue sarcoma retrospectively. We evaluated the efficacy and side effects of temozolomide in this patient group. RESULTS: This study involved 16 patients...

BACKGROUND: Ewing's sarcoma (EWS) is an aggressive small round cell tumor, affecting bone and soft tissues and is mostly seen in childhood and second decade of life. EWS accounts for 10-12% of bone tumors in more than 15 years age group and is even rarer after 40 years of age. MATERIALS AND METHODS: This retrospective analysis was conducted among patients aged more than 15 years with histologically proven EWS. RESULTS: Among 240 cases of EWS treated at our center during 2001-2010, 130 (54%) were more than 15 years of age...

AIM: To retrospectively study the therapeutic modalities of primary breast sarcomas in view of the data of a local Tunisian experience. METHODS: It is a monocentric, descriptive, retrospective study including 13 cases of primary breast sarcoma treated over a period of 25 years (1995-2020) in the oncological radiotherapy department of a university hospital in Sousse, Tunisia.

Tendon Sheath Giant Cell Tumor (TGCT) is a benign tumor that primarily grows within joints and bursae. However, it has a high postoperative recurrence rate, ranging from 15% to 45%. Although radiotherapy may reduce this recurrence rate, its applicability as a standard treatment is still controversial. Furthermore, the pathogenic mechanisms of TGCT are not clear, which limits the development of effective treatment methods. The unpredictable growth and high recurrence rate of TGCT adds to the challenges of disease management...

PURPOSE: Re-irradiation for bulky recurrent sarcoma carries significant risks. Pulsed low-dose rate radiotherapy (PLDR) is an attractive option for re-irradiation due to inherent radiobiological advantages. MATERIALS AND METHODS: We present two patients who underwent reirradiation using PLDR technique, followed by a literature review. RESULTS: The first case is that of a 76-year-old male who developed an in-field recurrence of a bulky pelvic bone high-grade chondrosarcoma after he was treated with definitive radiotherapy using helical TomoTherapy with a total dose of 66 Gy...

BACKGROUND: Bone tumors account for approximately 6% of all cancers in children. Malignant bone tumors, commonly occurring in children and adolescents, are associated with high mortality and morbidity. The overall survival of children with primary malignant bone tumors is affected by the stage of disease, time of diagnosis, and treatment response. Despite advanced treatment modalities with chemotherapy, surgery, and radiotherapy, bone tumor is the third leading cause of death in children with malignancy...

Surgery remains mainstay modality of treatment of STS of extremity. In majority of patients, primary closure is possible following surgical resection of the tumor. Primary closure of wound may not be feasible in tumors with large area of skin involvement and sometimes following a whoops procedure. We analyzed postoperative complications and oncological outcomes in patients who underwent free flap reconstruction. Thirty-seven patients who required a free flap for reconstruction of the defect following resection of the STS were included in the study...

Soft tissue sarcomas (STS) are a diverse group of malignant mesenchymal neoplasm.But, due to their low prevalence, very little data is available worldwide as well as in India regarding their clinico-epidemiological pattern.In this study we analysed the clinico-demographic profile of STS patients attending a tertiary care centre of Eastern India over the last 5 years. We analyzed the prospectively maintained database of a tertiary care centre of West Bengal in Eastern India, and collected the data regarding the demography, clinical profile, pathology and treatment of STS patients who attended our OPD between 2017-2021...

CASE REPORT: In a 74-year-old kidney transplant patient receiving immunosuppressive therapy, iatrogenic Kaposi's sarcoma (KS) developed in both lower eyelids. Subsequently, KS was confirmed in the region of the left forearm, with suspicion of lesions in the lungs. The ocular tumor was surgically removed with negative margins, requiring no further therapy...

PURPOSE/OBJECTIVE: This study aims to assess the prognostic value of the neutrophil-to-lymphocyte ratio (NLR) in soft tissue sarcomas (STS) treated with pre-operative hypofractionated radiotherapy (HFRT). MATERIALS/METHODS: This retrospective analysis included patients treated with pre-operative HFRT of 30 Gy in 5 fractions between 2016 and 2023. Clinical, demographic, and complete blood count (CBC) data were collected. NLR was calculated by dividing the absolute neutrophil count by the absolute lymphocyte count...

Postoperative radiotherapy for breast cancer reportedly increases the risk of thoracic soft tissue sarcomas, particularly angiosarcomas; however, the risk in the Japanese population remains unknown. Therefore, this study aimed to investigate the incidence of thoracic soft tissue sarcoma among patients with breast cancer in Japan and determine its association with radiotherapy. This retrospective cohort study used data from the population-based cancer registry of the Osaka Prefecture. The inclusion criteria were female sex, age 20-84 years, diagnosis of breast cancer between 1990 and 2010, no supraclavicular lymph node or distant metastasis, underwent surgery and survived for at least 1 year...

Ewing sarcoma is an exceedingly rare form of cancer that affects the cervix. It falls within the spectrum of neoplastic diseases known as Ewing's family of tumours, typically observed in osseous tissues. A woman in her 40s, experiencing symptoms of leucorrhoea and transvaginal bleeding that commenced 3 months before her consultation, was referred to our gynaecological oncology clinic with a preliminary diagnosis of ovarian teratoma. A colposcopy procedure was conducted unveiling a complete loss of cervical anatomy with friable and malodorous tissue...
