Aims and background Data from the literature show that the incidence of pelvic recurrences in poor prognosis endometrial carcinoma is significantly reduced by combined surgery and radiotherapy compared to surgery alone. Methods In this paper we analyze the results of the combined treatment surgery and adjuvant irradiation in patients with endometrial carcinoma with regard to survival, site of progression, and toxicity. The surgical treatment consisted of total abdominal hysterectomy and bilateral salpingo-oophorectomy in 40 patients. Pelvic and para-aortic node dissection was performed in 19 patients and lymph node sampling in 5. Results Overall 5-year survival was 85%. One patient had local failure, and 5 patients with local control of disease had distant metastases. Toxicity was mild and transient. Conclusions Our experience confirms the data of the literature. Postoperative irradiation is a safe and well-tolerated treatment that can achieve a good local control in high risk, stage I, endometrial carcinoma. The control of distant metastases remains an open question.

Aims and background. Medulloblastoma in adults is a rare tumor. The small number of cases in the reported series has not permitted a definite assessment of the prognostic role of clinical, pathologic and cell kinetics factors. The largest series of medulloblastoma in adults treated in a single institution is herein reported. Methods. The clinical, therapeutic, pathologic and proliferation features of medulloblastoma in 44 adult patients (> 18 years) were analyzed retrospectively with regard to postoperative survival. The proliferation potential of each tumor was evaluated by the immunohistochemical demonstration of proliferating cell nuclear antigen (PCNA) and Ki-67, clone MIB-1, in paraffin sections. Results. The overall 5- and 10-year survival rates were 40% and 35.6%, respectively. Significant factors in predicting a longer postoperative survival were: age < 37 years, decade of management (1977-1990), radiotherapy (50-55 Gy on the posterior fossa and 30-35 Gy on the spinal cord) and nuclear isomorphism. When corrected for adequacy of radiotreatment, desmoplastic type and differentiation were significantly correlated with a shorter survival. The PCNA-labelling index (LI) ranged from 34.5 to 82.2%, the MIB-1-LI ranged from 9.6 to 64.7%. No association was found between PCNA- or MIB-1-LI values and microscopic features, or between LI values and prognosis. Conclusions. Contrary to a general assumption, desmoplastic medulloblastoma and differentiated medulloblastoma are negative prognostic factors in adequately radiotreated adult patients. This may possibly be referred to lower radiosensitivity of these tumor variants. The LI with PCNA or Ki-67 is of no help in identifying aggressive tumors.

Aims The study was carried out to investigate the efficacy and toxicity of fludarabine phosphate in the treatment of B-cell chronic lymphocytic leukemia (B-CLL) in previously treated patients. Methods Sixteen patients, 11 males and 5 females, 9 in stage B and 7 in stage C, according to the Binet Staging System, were treated with a maximum of 6 cycles of fludarabine (25 mg/m2) for 5 days, every 4 weeks. All patients had been pretreated, 10 were refractory to standard regimens, 5 were in relapse, and 1 patient was in partial remission. Results Thirteen patients were judged suitable for evaluation. Overall 9 patients were responsive to treatment; 4 complete and 5 partial responses were observed. Of the 4 patients in complete remission, 3 were alive at 6, 10 and 13 months, respectively, from the beginning of treatment. One patient died after 11 months for acute graft-versus-host disease after allogenic bone marrow transplantation by an HLA sibling donor. Two of the 5 patients in partial remission were alive at 7 and 17 months, respectively, and the other 3 died (2 of disease reexpansion after 14 and 16 months and 1 of septic shock following pneumonia). Four patients were not responsive to treatment: 1 died from disease progression after 8 months from the beginning of therapy, 1 from cardiac failure after 9 months, 1 from septic shock following meningitis, and 1 was alive after 7 months of follow-up. Treatment was well tolerated, with nausea and vomiting in only one patient. We observed two episodes of pneumonitis, without any evidence of the responsible agent, a tumor lysis syndrome with acute renal failure, a recurrence of autoimmune thrombocytopenia, and a Coombs-positive hemolytic anemia. Conclusions Fludarabine phosphate is effective in the treatment of patients with advanced B-CLL, even in those refractory to multiple chemotherapy regimens.

Published: April 2018

Aims and background In addition to well-documented endocrine properties of interleukins, hemopoietic growth factors could also exert hormonal activities. In fact, our previous studies have shown that GM-CSF may stimulate cortisol and GH release. In contrast, few data only are available about the possible effects of G-CSF. This study was carried out to investigate endocrine effects of G-CSF in cancer patients. Methods The study included 8 cancer patients who were investigated after G-CSF (0.3 mg subcutaneously) or during saline infusion alone as control by collecting venous samples at zero time and after 2, 4, 6 and 8 h. Serum levels of cortisol, GH, PRL, FSH. LH, TSH and melatonin were measured by the RIA method. Results The circadian rhythm of cortisol was not influenced by G-CSF. No significant differences in mean levels of GH, PRL, FSH or LH were seen after G-CSF and during saline infusion. Both TSH and melatonin decreased after G-CSF, without, however, significant differences with respect to the values seen on saline alone. Conclusions The study showed that G-CSF has no substantial endocrine affects in humans. Therefore, G-CSF would differ from GM-CSF not only for its hemopoietic properties, but also from an endocrine point of view.

Aims and background Although they have been decreasing over time due to improved specificity of diagnostic assessment, benign biopsies of the breast are still common. Benign biopsies should be regarded as negative events, due to their economical and psychological cost and their possible negative impact on cosmesis and on further diagnostic evaluation. Methods Retrospective data on benign/malignant breast biopsies ratio (B/M) were collected in 9 Italian centers for a period of 10-15 years. The time trend of B/M and its association to age or to single centers was evaluated. Results Overall 31,001 cases were considered. A strong association of B/M to age was evident (average B/M values were 5.0, 1.3, 0.6, and 0.2 for women aged <40, 40-49, 50-59, and >59 years). A significant trend of decreasing B/M over time was observed only for one center. Age standardized B/M was significantly different (P<0.000001) between centers, ranging between 0.34 and 1.69. Multivariate analysis confirmed an independent significant association of age and center to B/M. Conclusions Marked differences in B/M are evident between centers, which cannot be explained by the confounding effect of age or by any apparent difference in the diagnostic protocol. The observed differences are likely ascribed to individual variations in diagnostic aggressivity. A progressive increase of the predictive value of calls for surgical biopsy may be achieved over time and centers with a high B/M should make every effort to optimize their performance. Acceptable (<40=5, 40-49=1.5, 50-59=0.75, >59=0.3) and desirable (2.5, 0.75, 0.35, 0.15) age specific reference standards for B/M are proposed.

Aims and Background The role of radiotherapy in the management of patients with optic pathway tumors remains controversial. This study analyzes the outcome of patients treated with radiotherapy and attempts to identify the groups of patients that may require early therapy. Methods We retrospectively reviewed 36 patients with optic pathway tumors treated with radiotherapy alone (26 patients) or with postoperative radiotherapy (10 patients). Seven patients had optic nerve tumors and 29 patients had chiasmal tumors. The actuarial progression free survival and observed survival probabilities were calculated using the Kaplan-Meier method and differences between curves were evaluated by the Mantel-Cox test. The obtained significant variables in the univariate analysis were analyzed using the Cox proportional hazards model. Results The 10-year actuarial progression-free survival (10-y PFS) rate was 86% for patients with optic nerve gliomas and 47% for patients with chiasmal tumors. The 10-year actuarial observed survival (10-y OS) rate was 75% for patients with optic nerve gliomas and 53% for patients with chiasmal gliomas. In the group of patients with chiasmal tumors, progression-free survival and observed survival rates were significantly lower in infants (10-y PFS: 30%; 10-y OS: 37%), in patients with neurological deficits (10-y PFS and 10-y OS: 23%), in patients with signs of elevated intracranial pressure (10-y PFS and 10-y OS: 9%), with hydrocephalus (10-y PFS and 10-y OS: 0%), or with impairment of consciousness (10-y PFS and 10-y OS: 17%). Evaluation by computed tomography scanning was associated with a significantly higher probability of PFS. Radiation doses lower than 50 Gy were associated with significantly lower PFS and OS rates. In the Cox multivariate analysis, presence of neurological deficits and radiation dose significantly influenced observed survival. Presence of hydrocephalus significantly influenced progression-free survival. Conclusions The prognosis of patients with chiasmal gliomas presenting with neurologic deficits is poor and should be treated at diagnosis. A minimum tumor dose of 50 Gy is recommended.

Aims and background To evaluate the response rate, toxicity and survival of patients with AIDS-related Kaposi's sarcoma (AIDS-KS) treated in a phase II clinical trial of pentosan polysulpate (PPS), an inhibitor of basic-fibroblast growth factor (b-FGF) which blocks the growth of Kaposi's sarcoma cells both in culture and in animal models. Patients and methods Between March 1992 and March 1994 16 homosexual males with histopathologically confirmed AIDS-KS were accrued for this phase II clinical trial. PPS was administered at the dose of 25 mg/m2 q6 hrs at day 1, followed by 25 mg/m2 q12 hrs daily by a subcutaneous injection. The number of patients to be included in the trial was calculated according to the two-stage Gehan method. Toxicity was graded according to the NCI Common Toxicity Criteria, while responses were evaluated according to the WHO Criteria adapted for KS lesions. Patients were all homosexual males, median age 35 (27-43) years, performance status (WHO) 1 (0-2), NYU stage II-IV and prior therapy included vincristine and etoposide (3 cases), local irradiation (4 cases) and meges-trol acetate (2 cases). Concomitant AZT (zidovudine) was given to 3 patients, while DDI (dideoxyinosine) was administered in one case. Results A median of 5 (3-11) weeks of therapy was administered to the patients. Pain at the injection site and low grade fever were the only toxicities observed. Drug-related effects on coagulation parameters or thrombocytopenia were not observed in the trial. One objective response (6%) was documented, which lasted for 9 weeks, while stable disease was observed in three patients, lasting for 11, 9 and 5 weeks, respectively. Conclusion This is the first observation of objective antitumor activity with a b-FGF inhibitor in patients with AIDS-KS. Considering its novelty and the lack of significant toxicity, the authors suggest that this experimental approach deserves further evaluation.

Published: April 2018

Aims and background The treatment of elderly patients with metastatic solid tumours is still a debated problem. Patients over 75 years are generally excluded from combination chemotherapy trials because of higher toxicity. Several clinical studies have shown that weekly low dose epirubicin is a well tolerated and effective treatment for elderly cancer patients (breast, prostate, lung). Methods We report a study of patients aged between 75 and 85 years affected by metastatic anthracyclines-sensible carcinomas, to assess the tolerance of epirubicin given weekly at a dose of 25 mg/m2. Results 25 patients (13 males, 12 females; ECOG P.S. 0-2) entered the study and were evaluable for side effects. One-hundred and ninety-six cycles of therapy have been administered. Side effects were never severe. Mucositis (9 patients), leucopenia (7 patients), anemia (5 patients) were usually of grade 1 or 2. Grade 1 cardiotoxicity (tachycardia) was observed in only one case. Grade 3 toxicity consisted in anemia (1 patient) and mucositis (1 patient), while grade 4 toxicity never occurred. Nineteen patients were evaluable for response: 0 CR, 4 PR (1 lung, 3 breast), 8 SD (3 lung, 3 breast, 2 prostate) have been observed. Compliance was encouraging and the majority of patients showed a decrease in symptoms and an improvement in performance status. Conclusions Weekly low-dose epirubicin is a very well tolerated treatment in elderly cancer patients. In view of the negligible toxicity encountered, it could be of utility to test this regimen in patients aged 75 years or older, affected by anthracyclines-sensible metastatic tumors, also to assess activity.

Published: April 2018

Aims and background Vascular access through a vein draining into the superior vena cava is commonly used for long-term infusion of drugs inr cancer chemotherapy; prolonged cannulation of the inferior vena cava is generally considered as having an excessively high complication rate. Methods Prolonged cisplatin infusion via the inferior vena cava by means of a Groshong catheter was evaluated in 20 consecutive patients with thoracic malignancies showing evidence of superior vena cava infiltration or obstruction. Results We achieved 1,291 catheter days for our survey with a mean duration of vascular access of 64.5 days per patient and a mean duration of infusion time of 40 days. There were 2 complications, a catheter obstruction after a 7-day rest period and an ileo-femoral thrombosis 6 days after catheter placement. Conclusions Our experience compared favourably with the results obtained by long-term central venous access via the supraumbilical route, and demonstrated the reliability and safety of this approach in cases where the superior vena cava cannulation is technically difficult or impossible.

Published: April 2018

Aims and Background Various attempts have been made to prevent 5-fluorouracil-induced stomatitis, with unsatisfactory results. Sucralfate is an aluminum hydroxide, complex of sulfated sucrose commonly used in the treatment of gastroduodenal ulcers. We used the compound in a phase II study to reduce and minimize the stomatotoxicity of 5-fluorouracil chemotherapy administered in a multiple-day schedule. Methods Fifty-two patients entered the study, and 129 cycles of chemotherapy were evaluated. Seven patients refused sucralfate rinses for taste intolerance. Results A low level of stomatotoxicity was recorded: grade 2 stomatitis was observed after 14 cycles (10.8%) and grade 3 after 3 cycles (2.3%). Conclusions Sucralfate administration could have a role in the prevention of 5-fluorouracil-induced stomatitis.

Published: April 2018

Aims To analyze the radiologic characteristics, clinical course and long-term follow-up of 7 radiologically uncommon pediatric cases of Langerhans cell histiocytosis and to identify prognostic factors related to imaging patterns. Methods The clinical records and complete imaging data of 75 patients with LCH diagnosed and treated at the National Cancer Institute of Milan between January 1975 and December 1993 were analyzed, and 43 cases presenting as unifocal bone lesions were identified. The plain film, computed tomography and magnetic resonance characteristics enabled the identification of 7 radiologically aggressive and rapidly progressive cases, which were analyzed at presentation and during follow-up. Results Although at disease presentation bone lesions appeared lytic destructive, rapidly progressive and often involved adjacent soft tissues, after adequate therapy the disease course was invariably benign and led to almost complete restoration of normal structure and function. Long-term follow-up confirmed the favorable outcome and lack of disease recurrence in all cases. Conclusions There is no correlation between radiologically aggressive characteristics and final outcome in Langerhans cell histiocytosis. Radiologists and pediatric oncologists should be acquainted with less common radiologic forms which, at presentation, can mimic more ominous diseases. If recognized and adequately treated, monostotic forms almost invariably have a benign prognosis.

Published: April 2018

Aims and background To review the clinical, radiological and histological findings of 19 patients with radiation-induced intracranial meningiomas treated at our neurosurgical department between 1981 and 1996. Method The records of 18 patients with intracranial meningiomas who underwent low-dose radiation for tinea capitis in childhood, and of one patient irradiated for pituitary adenoma, were analyzed in respect of the previously reported features of postradiation meningiomas. Results The mean age of the patients with low-dose radiation-induced meningiomas was 58 years and the mean shortest onset latency was 48 years. The male to female ratio was 1.1:1. Forty-seven percent of patients presented with mental changes and/or focal neurological signs, 21% with signs of increased intracranial pressure and 26% with seizures. Calvarial location of the meningiomas was found in 54% of patients and in one patient the tumor arose from the skull base. Multiple tumors were present in 15% of patients and 29% of the meningiomas displayed malignant features on histological examination. A significantly lower meningioma recurrence rate was found in our series compared to the recurrence rate in the reported series of postradiation meningiomas. Five patients had a history of a second neoplasm other than meningioma. Conclusion Our series of low-dose radiation-induced meningiomas represents one of the largest of its kind in the English literature. The patients did not differ substantially in sex ratio, tumor localization, multiplicity and histological features from the previously reported postradiation meningioma patients, except for the significantly lower tumor recurrence rate. It would seem that over the next years we will be further witnessing the deleterious effects of low-dose radiation administered in childhood.

Published: April 2018

Aims and background An evaluation of the Bologna Hospital-at-Home (BHH) was undertaken to examine the following aspects: 1) median daily costs of the BHH; 2) delivery of medical services; 3) patient satisfaction with the care received and frequency of requests for transfer to the alternative setting. Delivery of services and patient's satisfaction in the BHH were compared with data collected for a traditional hospital (Ospedale Sant'Orsola Malpighi, Bologna - OSM). Methods Our analysis was performed as a cost analysis considering two periods of time in 1992 and 1993/94. Included were direct and indirect costs; no intangible costs were found. The patient's perspective was selected for the analysis. The observational study examining delivery of service and quality of life of patients admitted to the two care settings, BHH and OSM, considered patient's clinical history and an interview conducted by the evaluation team 6 weeks after admission to either facility. Data included patient's characteristics, quantity of diagnostic and therapeutic measures, circumstances of life, satisfaction with the care received, and intention for transfer to the alternative setting of nursing. The statistical significance of our assumption of comparable care intensity and better patient quality of life in the BHH was tested by the Pearson Chi-square test. Results A survey was carried out of 236 patients treated in the BHH or the OSM. The setting of assistance did not influence the provision of services. The time of “talking to the doctor” was notably higher for BHH than for OSM patients. The analysis of satisfaction showed that 98% of the surveyed BHH patients believed it matched the actual needs. The quality of life was considered to be reduced/bad in 67% of the OSM patients but in only 51% of BHH patients. An opinion was also requested with regard to transfer to the alternative setting of nursing: 47% of OSM patients judged BHH care would be better than traditional hospital. The median daily costs in BHH reached 118,789 Lire (range, 108,569-129,027 Lire, depending on performance status). Conclusions Although the economic advantage of hospital-at-home care certainly is important, we would like to stress that better quality and dignity of life should be the main point supporting the idea of hospital-at-home care.
