Radiation Therapy in Non-Melanoma Skin Cancers: An Italian Survey on Behalf of the Italian Association of Radiotherapy and Clinical Oncology.

AIMS: The National Palliative Care and Interventional Radiotherapy Study Groups of the Italian Association of Radiotherapy and Clinical Oncology (AIRO) carried out a survey whose aim was to obtain a "snapshot" of the real-world practice of nonmelanoma skin cancer (NMSC) treatments in Italy. MATERIALS AND METHODS: The survey was conducted on SurveyMonkey's online interface and was sent via e-mail to our society Radiation Oncologists. RESULTS: Fifty-eight Italian radiation oncologists (ROs), representing 54 centers, answered the survey. Thirteen percent of the ROs declared they treat fewer than 10 NMSC lesions annually, 36% treat between 11 and 20, and 51% treat more than 20 lesions annually. Interventional radiotherapy (IRT) was offered by 25% of the ROs, and every case was reportedly discussed by a multidisciplinary team (71%). Electrons (74%), volumetric modulated arc therapy (V-MAT) (57%), three-dimensional conformal radiotherapy (3D-CRT) (43%), and IRT (26%) were the main treatment options. With external beam radiotherapy (EBRT), 46 and 53 different RT schedules were treated for curative and palliative intent, respectively; whereas for IRT, there were 21 and 7 for curative and palliative intent, respectively. The most popular EBRT curative options were 50-70.95/22-35 fractions (fx) and 50-70 Gy/16-20fx and for EBRT palliative settings, 30Gy/10fx, and 20-35Gy/5fx. For IRT, the most popular curative options were 32-50Gy/8-10fx and 30-54Gy/3-5fx, whereas 30Gy/6fz was the palliative option. Less than 10 re-RT cases were reported in one year in 42.5%, 11-20 cases in 42.5%, and >20 cases annually in 15%. Electrons (61%), VMAT (49%), and BRT (25%) were the most widely used approaches: 20-40Gy in 10fx and 20-25Gy in 5fx were the recommended fractionations. CONCLUSION: The survey shows a variegated reality. A national registry with more detailed data could help in undercover its causes.

The role of radiotherapy in Kimura's disease: a multicenter systematic review of literature.

OBJECTIVE: From a clinical point of view, Kimura's disease is typically characterized by a subcutaneous mass occurring predominantly in the head and neck region. It occurs predominantly in young men of Asian descent, with a peak incidence in the second and third decades of life. However, KD has been also reported in other ethnic groups and in children. The most frequently used local treatments are surgical excision, radiotherapy, and surgical excision followed by radiotherapy. The aim of this multicenter systematic review is to highlight the available literature evidence about the outcome of RT in this setting. MATERIALS AND METHODS: A systematic review of any relevant literature in the principal medical databases, such as PubMed, Scopus and Cochrane library, was conducted. The inclusion criteria were original articles specifically reporting about KD and RT, including both prospective and retrospective studies. RESULTS: We were able to identify 11 studies, published from 1989 to 2021, eligible for inclusion in this review. Overall, data on 124 patients were recorded and are presented in this systematic review. The median recurrence rate, considering all patients, was 11% (ranging from 0% to 41.2%). In seven out of 11 studies, the relapse rate was less than 20%. Moreover, the relapse rate was 0% in four studies. CONCLUSIONS: The results of this multicenter systematic literature review show that evidence on RT of KD is limited and derives only from retrospective studies. In this setting RT seems to be well-tolerated and able to produce very high response rates in unresected lesions and reasonable results in terms of local control both as an exclusive and adjuvant treatment.

[The role of radiotherapy in the management of patients with small cell lung cancer]. / Place de la radiothérapie dans la prise en charge des carcinomes bronchiques à petites cellules localisés.

Small cell lung carcinomas are aggressive on account of their high and early risk of dissemination. They represent less than 20% of all lung cancers and only a third of these present with limited stage disease at diagnosis. Currently, treatment is based on synchronous thoracic irradiation and chemotherapy combining platinum salts and etoposide with or without other drugs. Because of the high risk of brain metastases, prophylactic cranial irradiation (PCI) is indicated in patients with a complete response and should be part of the standard management of these patients on the basis of a meta-analysis showing a 5% increase in survival at three years. In limited stage disease 5 year survival rates can reach 25% but the majority of patients will relapse. This progress is the consequence of a better combination of thoracic and cerebral irradiation and polychemotherapy. Even in extensive disease PCI reduces the risk of brain metastases and significantly improves overall survival. Many issues are subject to further clinical research concerning modalities of combination radio-chemotherapy, radiotherapy target volumes, optimum dosage, and the use of drugs in association with irradiation.

Unresectable hilar cholangiocarcinoma: multimodality approach with percutaneous treatment associated with radiotherapy and chemotherapy.

Klatskin-type cholangiocarcinoma is a rare tumor, bearing a very poor prognosis: at diagnosis, most patients can only undergo palliation. Evaluation of outcome, mean survival and quality of life was performed in patients with unresectable hilar cholangiocarcinoma treated with multimodality approach in comparison with surgical palliation, biliary stenting or brachytherapy alone. Twenty-six patients with hilar cholangiocarcinoma were studied: 16 patients were enrolled in the multimodality protocol (bilateral biliary drainage; Iridium-192 brachytherapy; plastic endoprosthesis or metallic stent positioning and external radiotherapy plus systemic chemotherapy), 5 patients underwent surgical palliation and 5 percutaneous decompression alone. Nine patients completed the protocol and 7 were treated with brachytherapy followed by biliary stenting alone. The multimodality approach obtained mean survival (10 months) similar to that for surgery and higher than that of the brachytherapy and metallic stenting groups (6 and 2.75 months, respectively). The average hospital stay (15 days) was lower than that of the surgical group (20 days). A multimodality approach is a suitable alternative to palliative surgery of unresectable hilar cholangiocarcinoma.

[Appendiceal mucocele associated with colonic neoplasm. Report of 2 cases and review of the literature]. / Mucocele appendicolare associato a neoplasia del colon. Presentazione di due casi e revisione della letteratura.

Appendiceal mucocele is a rare entity frequently associated with colorectal cancer. We report two cases of mucocele associated with colorectal tumours. The first case (male, 64 yrs) is an appendiceal mucinous cystadenoma found incidentally during surgery for colon cancer. There is no evidence of disease after a 4-year follow-up. The second case (male, 66 yrs) is a mucocele associated with mucosal hyperplasia that was found during surgery for acute appendicitis with a periappendicular abscess. Endoscopic follow-up showed a rectal adenocarcinoma that was initially treated with local excision with T.E.M.. Examination of the pathology specimen documented vascular invasion and the patient underwent curative colorectal resection. The preoperative radiological and endoscopic diagnostic procedures and the current therapeutic approaches described in the literature are reviewed. The relevance of the association between appendiceal mucocele and colorectal cancer is emphasized. Thorough investigation of the colorectal tract is recommended after diagnosing an appendiceal mucocele.

[Endometriosis of umbilical cicatrix: a clinical case]. / Endometriosi della cicatrice ombelicale: un caso clinico.

The Authors report a case of umbilical endometriosis in a 46-year-old patient. The woman came in for observation describing acute pain in the vicinity of the umbilical scar. The pain was occasional at first and then became steady and increased at the time of menstruation. Medical examination revealed a left paraumbilical nodule, measuring 1 cm in diameter. The patient underwent surgical treatment: the nodule was excised and the subsequent histological examination was diagnostic for umbilical endometriosis. The surgical excision was effective: at follow-up 3 months later, there was no recurrence and the patient was in good general condition.

[Bilateral pheochromocytoma associated with duodeno-jejunal GIST in patient with von Recklinghausen disease: report of a clinical case]. / Feocromocitoma bilaterale associato a GIST duodeno-digiunale in paziente affetto da malattia di von Recklinghausen: presentazione di un caso clinico.

The authors present the case of a 60-year-old male patient suffering from von Recklinghausen's disease (neurofibromatosis type I, NF1) with bilateral pheochromocytoma and occasional intraoperative reports of duodenojejunal GIST (GastroIntestinal Stromal Tumour). Through a review of the literature the authors analyze the frequency and the features of bilateral pheochromocytoma and its rare histological variant, the so-called composite pheochromocytoma, characterized by the combination of pheochromocytoma and ganglioneuroma or ganglioneuro-blastoma. Bilaterality of pheochromocytoma is more frequent in patients with familiarity for pheochromocytoma without NF1. Composite pheochromocytoma accounts for about 3% of total pheochromocytomas. In addition, the authors summarize the present knowledge about gastrointestinal stromal tumours and investigate the possible association between them and NF1 or pheochromocytoma, concluding that any such association is purely casual, while confirming the well known, genetically determined association between NF1 and pheochromocytoma.

[Perforated diverticulum of the cecum: a difficult preoperative diagnosis]. / Diverticolo perforato del cieco: una diagnosi preoperatoria difficile.

A patient was admitted for a suspected appendicitis; occasionally, a roentgenogram of abdomen, an echography and a tomography: confirmed the suspect. At laparotomy a perforated diverticulum of cecum is suddenly reported: a segmentary resection of ascending colon is performed. Authors remark, according to literature, that preoperative diagnosis of perforated cecal diverticulum is difficult even today, in spite of diagnostic procedures.

[Splenic epidermoid cyst. Clinical case and review of the literature]. / Cisti epidermoide della milza. Caso clinico e revisione della letteratura.

The occasional discovery of an epidermoid cyst of the spleen, rare kind of lesion, in a 25 years old man who underwent a US for urethral colic, permit to the authors a review of the literature. Treatment is individualized in a partial or total splenectomy.

[Gastric neoplasia in pregnancy: report of a case]. / Neoplasia gastrica in gravidanza: case report.

CASE REPORT: Gastric cancer in a 29 years old pregnant woman. A total of 109 cases were collected in the whole from 1916 to 1988; to these, we add one new case of a 29 years old pregnant woman observed in 1993 in Verona University Surgical Sciences Department. DISCUSSION: Cancer of the digestive tract during pregnancy is really rare and has poor prognosis. The diagnosis during pregnancy is difficult because the symptoms are frequently masked by factors related to the normal first trimester in pregnancy. X-ray are often restricted. Gastroendoscopy is applied to pregnant women only when evident symptoms are present such as: severe anemia, jaundice and weight loss. The incidence of inoperable cases is elevated such as the mortality in the operated cases. The whole survival rate after three years is 21%. CONCLUSION: Gastric cancer in pregnancy has a poor prognosis. The possible reasons are: delayed detection, low differentiation degree, restricted therapeutic approach because of pregnancy, personal factors as the patients' desire for a child, religious, ethical considerations.

Submucosal reconstructive hemorrhoidectomy (Parks' operation): a 20-year experience.

BACKGROUND: Submucosal reconstructive hemorrhoidectomy has never been a popular operation due to its difficulty and duration, the amount of blood loss, and the risk of incontinence. The main indication for hemorrhoidectomy according to Parks is fourth-degree hemorrhoids with prolapse of the dentate line outside the anus and with simultaneous presence of external hemorrhoids. We report our experience in the treatment of hemorrhoids using submucosal reconstructive hemorrhoidectomy according to Parks. METHODS: A total of 640 patients (381 men and 259 women) of median age 42 years (range, 18-81) were treated between 1983 and 2002; 80% of patients had fourth-degree, 19% third-degree and 1% second- degree hemorrhoids. All patients underwent rectosigmoidoscopic examination before surgery; patients over 35 years of age or with a suspected inflammatory or neoplastic disease underwent colonoscopy or barium enema. All patients underwent anorectal manometry before operation, to measure anal resting pressure, maximal squeeze and sphincter length, with the purpose of determining if an internal sphincterotomy was also necessary (in case of high anal resting tone). One-third of the patients also had an internal sphincterotomy to correct anal hypertonia. RESULTS: Postoperative bleeding occurred in 19 patients (2.9%), 0.9% requiring a reintervention. Severe pain was reported by 9 patients (1.4%); fecal impaction occurred in 3 cases (0.5%) and suture disruption in 2 patients (0.3%). In 74 patients (11.6%), bladder catheterization was needed due to urinary retention. Of 550 patients who had a minimum follow-up of 3 years and were sent a postal questionnaire, 374 patients responded, with a median 7.3-year follow- up; 176 patients (32%) were lost to follow-up. Eleven patients (2.9% of 374 cases) reported pain during defecation, 6 (1.6%) developed skin tags or recurrence, 3 (0.8%) reported gas incontinence, 2 (0.5%) developed anal fistula and 1 (0.3%) had anal stricture. CONCLUSIONS: Submucosal reconstructive hemorrhoidectomy according to Parks still represents a good choice for the treatment of high-degree hemorrhoids with prolapse of the dentate line outside the anus and external circumferential hemorrhoids.
