Epithelioid sarcoma (ES) was first described by Enzinger in 1970. It is a rare variant of soft tissue sarcoma with a 5-year overall survival (OS) rate of 50%. Here, we reported a case of epithelioid sarcoma in the parapharyngeal space of an adult, resulting in a favorable prognosis after chemotherapy and radiation therapy. A 34-year-old female who complained of pharynx pain and discomfort was suspected of having a tumor in the right parapharyngeal space by CT scan. Excision biopsy suggested epithelioid sarcoma. Clinical and radiological studies did not reveal tumor distant metastasis in the patient. After excisional biopsy, the patient underwent chemotherapy and external beam radiation treatment. She has remained alive for 2 years and 7 months without recurrence since her last treatment. In this paper, we also provide a detailed review of the role of radiotherapy in the treatment of epithelioid sarcoma in previously reported cases.

Male Predominance

Epithelioid sarcoma is a rare high-grade malignancy identified by Enzinger in 1970. It accounts for 1% of all reported soft tissue sarcomas and presents most commonly in distal upper extremities in young adults with a male predominance. At this time, there are only 5 previously reported cases of primary epithelioid sarcoma of the orbit. We present a primary orbital epithelioid sarcoma case of a patient who underwent orbital exenteration followed by external beam radiation treatment. Because the literature is limited, this is to our knowledge the largest descriptive analysis of cases of orbital epithelioid sarcoma. We also provide a detailed review of all the previously reported primary orbital epithelioid sarcoma cases, as well as a discussion on the use of postoperative radiation therapy for patients with epithelioid sarcoma. Surgical resection followed by adjuvant radiation therapy appears to be a safe option for local treatment of this rare malignancy, but further future studies are needed of this rare clinical situation in order to better understand and optimize treatment for patients with orbital epithelioid sarcoma.

Radiation Technique

Medullary thyroid cancer (MTC) is a neuroendocrine tumor derived from parafollicular or C cells of the thyroid gland. Surgical resection is the mainstay of treatment for MTC. External-beam radiation treatment (EBRT) has traditionally played a limited role in the management of MTC. Despite aggressive surgery, patients at high risk for local recurrence may benefit from adjuvant EBRT. With improvements in radiation technique, adequate dose can be effectively delivered to the region at risk while minimizing dose to surrounding critical structures. Although the role of EBRT in the management of these tumors has thus far been poorly defined, EBRT should be considered as a treatment option for patients with locally advanced MTC to optimize locoregional control.

ABSTRACT OBJECTIVE Advanced age is a strong predictor of shorter survival in patients with glioblastoma multiforme (GM), especially for those who receive multimodality treatment. Radiographically assessed tumor response to external beam radiation therapy is an important prognostic factor in GM. We hypothesized that older GM patients might have more radioresistant tumors. METHODS We studied radiographically assessed response to external beam radiation treatment (five-level scale) in relation to age and other prognostic factors in a cohort of 301 GM patients treated on two prospective clinical protocols. A total of 223 patients (74%) were assessable for radiographically assessed radiation response. A proportional odds ordinal regression model was used for univariate and multivariate analysis. RESULTS Younger age (P = 0.006), higher Karnofsky Performance Scale score before radiotherapy (P = 0.027), and more extensive surgical resection (P = 0.028) predicted better radiation response in univariate analyses. Results were similar when clinical criteria were used to classify an additional 61 patients without radiographically assessed radiation response (stable versus progressive disease). In multivariate analyses, age and extent of resection were significant independent predictors of radiation response (P < 0.05); Karnofsky Performance Scale score was of borderline significance (P = 0.07). CONCLUSION Older GM patients are less likely to have good responses to postoperative external beam radiation therapy. Karnofsky Performance Scale score before radiation treatment and extent of surgical resection are additional predictors of radiographically assessed radiation response in GM.

A 51-year-old woman complained of intermittent nasal obstruction and rhinorrhea. Sinus roentgenograms and polytomograms revealed a small mucocele of the right sphenoid sinus. There was no encroachment of the orbital apex or intracranial contents. The mucocele was marsupialized via an external ethmoidectomy, and the scant tissue present inside the sinus was examined histologically. The pathologic diagnosis was hemangiopericytoma. The small tumor had apparently originated at the sinus ostium, thus creating the mucocele. Several months postoperatively, a small, vascular tumor nodule was noted in the incision. No recurrence was evident intranasally. A course of 5,040 rads of external beam radiation therapy was given to the right ethmoid labyrinth and right sphenoid. Since completing her radiation therapy, there has been no recurrence. This case is of interest because the tumor occurred as a mucocele of the sphenoid sinus.

Post Radiation

External beam radiation therapy is widely used by doctors around the world as one of the most common form of cancer treatment. The radiotherapy can help reduce the treatment aggression as compared with the surgical intervention in a large number of clinical situations, which ensures that the patient's quality of life will be decreased to a lesser extent in the after-treatment period. However, like the vast majority of anticancer treatments, the radiation therapy has a number of side effects, which are classified into acute radiation reactions and post-radiation injuries. Among them is radiation dermatitis, which is one of the most common adverse reactions to the radiotherapy. This complication manifests as erythema, as well as hyperpigmentation, dry and itchy skin, hair loss. In addition to the obvious negative impact on the patient's quality of life, some of the above factors can result in the development of a secondary skin infection. As one of the most frequent post-radiation complications, radiation dermatitis places radiotherapists before a challenge to reduce the incidence rates of this side effect, as well as to decrease the intensity of its clinical manifestations if it occurs. This challenge suggests the search for targeted drugs aimed to prevent and treat clinical symptoms. To date, dermatocosmetic products that are used to relieve skin manifestations of radiation treatment complications is an alternate option of the effective solution to the problem of radiation dermatitis. In the described clinical case, we assess the experience of using some of the dermatocosmetic products in a patient with a florid form of radiation dermatitis.

Background: The purpose of this study is to detect a correlation between the preradiation tumor staging and the relative volumetric regression of the primary tumor through external beam radiation therapy (EBRT). Methods: Clinical data of 32 patients with a mean age of 60±12 years treated with primary radiation therapy (RT) of cervical carcinoma were analyzed. Union Internationale Contre le Cancer (UICC) stages were T1 = 4 patients, T2 = 15 patients, T3 = 8 patients, T4 = 5 patients; N1 = 26 patients, N0 = 6 patients; and M0 = 25 patients, M1 = 7 patients. All patients received pelvic magnetic resonance imaging (MRI) before RT as well as during RT. The cervical primary tumor was delineated as gross tumor volume (ptGTV) in T2-weighted MRI sequences. We compared ptGTV reduction by stage, lymph node status, metastatic status, and grading. Results: Mean ptGTV reduction during RT was 61.4±28.9%. T1 tumors shrank by 88.2±13.4%, T2 by 67.6±28.7%, T3 by 50.8±23.6%, and T4 by 38.7±27.2%. The difference in tumor shrinkage was statistically significant between the lower T stages and the higher T stages ( p < 0.05). There was no statistical difference in the mean ptGTV before treatment in the group with lymph node metastases (LNM) (54.1±47.7 cm3) as compared to the group without LNM (76.6±52.2 cm3). Nonetheless, ptGTV shrank significantly differently: by 68.9±25.7% (N1 patients) and by 29.0±17.7% (N0 patients). No significant differences in ptGTV shrinkage were observed in M0 versus M1 and G2 versus G3 tumors. Conclusion: There is a correlation between mean ptGTV reduction during EBRT and tumor stages. Tumors with higher T stages shrank less under radiation treatment, and the ptGTV of N1 patients responded better than that of N0 patients.

Mean Time

The purpose of this study is to report clinical aspects and treatment results of patients seen at Johns Hopkins. A search of the tumor registry of the Sidney Kimmel Comprehensive Cancer Center found 453 patients with malignancies of the vulva registered between 1977 and 1997. Patient and tumor characteristics, treatment methods, and follow-up were obtained from charts. Seven patients were identified with sarcoma of the vulva. Of these, one was removed from analysis due to histology. Three patients had leiomyosarcoma, two had fibrosarcoma, and one had epithelioid sarcoma. The mean age was 41. Mean time to diagnosis was 6 months. All but one of the tumors was located on the labia majora. Median tumor size was 3.5 cm. Surgery varied from wide local excision to radical vulvectomy with inguinal lymph node dissection. Surgical margins were microscopically negative in five of the six cases. Two patients had received adjuvant external beam radiation. One of them had a tumor greater than 5 cm and close surgical margins and the other had high-grade tumor, which recurred after previous surgery. Mean follow-up was 127.8 months. There have been no recurrences to date.
