Hypovolemic shock due to giant uterus leiomyoma detachment.

Uterine leiomyoma (UL) is the most common benign gynecologic tumor of the reproductive age females. It is symptomatic only in 25% of the patients causing dysmenorrhea, menorrhagia or anemia. In some patients it occurs just as a palpable abdominal mass. In this study, we report a 50-year-old woman with a giant mass, attached to the uterus, which was detached and therefore led to shock due to major hemorrhage. Surgical removal of both the mass and the uterus confirmed the diagnosis of a pedunculated uterine leiomyoma.

Increased androgen bioavailability is associated with non-alcoholic fatty liver disease in women with polycystic ovary syndrome.

BACKGROUND: Increased prevalence of abnormal aminotransferase levels and/or ultrasonographic evidence of hepatic steatosis (HS) have been found in women with polycystic ovary syndrome (PCOS). However, factors associated with non-alcoholic fatty liver disease (NAFLD) in PCOS are still under investigation. The aim of this case-control study was to investigate the presence of NAFLD and to assess factors associated with this condition in PCOS patients. METHODS: A prospective study of 57 premenopausal PCOS patients and 60 age- and weight-matched control women, with a history of no or minimal alcohol consumption was conducted. Anthropometric variables, biochemical and hormonal parameters were determined and NAFLD was evaluated by abdominal ultrasonography and biochemical testing, after excluding causes of secondary liver disease. Insulin resistance was assessed by homeostasis model assessment of insulin resistance (HOMA-IR) and free androgen index (FAI) was calculated. RESULTS: PCOS patients had an increased prevalence of HS [21/57 patients (36.8%) versus 12/60 controls (20.0%), P < 0.05] and abnormal (> or =40 IU/l) serum aminotransferase levels [13/57 patients (22.8%) versus 2/60 controls (3.3%), P < 0.01] than controls. All patients and controls with metabolic syndrome had HS. Factors associated with HS were PCOS diagnosis, older age, increased BMI, waist circumference (WC), HOMA-IR and FAI values and decreased high-density lipid cholesterol and sex hormone binding globulin levels. PCOS patients had an OR of 3.55 (95% CI: 1.02-5.35) for HS versus controls, after adjustment for age, BMI and WC. CONCLUSIONS: NAFLD is common in PCOS patients and increased androgen bioavailability may be implicated, in combination with metabolic abnormalities. Liver evaluation is proposed in PCOS patients, especially in those with metabolic syndrome.

Outcome of patients receiving photodynamic therapy for early esophageal cancer.

PURPOSE: Photodynamic therapy (PDT) has shown remarkable activity in a variety of human cancers. In the present study, we report the effects of PDT on inoperable early-stage esophageal cancer. METHODS AND MATERIALS: Sixty-two patients were treated with an argon dye laser (630 nm wavelength, 300-800 mW of power, energy dose of 200-300 J/cm) after intravenous injection of 5 mg/kg of hematoporphyrin derivative. Eighteen patients (29.5%) had in situ carcinoma (Tis), 30 (48.5%) had T1-stage cancer, 7 (11%) had T2-stage cancer, and 7 (11%) had recurrent disease in the anastomotic area after previous surgery without evidence of invasion outside the lumen. Patients with residual disease after two rounds of PDT received definitive radiotherapy. Patients were evaluated for response to therapy and survival. The follow-up time ranged from 3 to 90 months (median, 32 months). RESULTS: The complete response (CR) rate was 37% (23 of 62) in patients who received PDT alone and 82% (51 of 62) in those who also received radiotherapy. The CR rate after PDT alone was statistically higher (p = 0.04) for patients who had Tis/T1 lesions (21 of 48; 44%) than for those with T2-stage disease (2 of 7; 28%) or recurrent tumors (0 of 7; 0%). Fifty-two percent of patients who had CR following PDT alone did not suffer local tumor recurrence. The median local progression-free survival times after PDT and additional radiotherapy (in cases with incomplete response) was 49 months for Tis- and T1-stage lesions, 30 months for those with T2-stage disease, and 14 months for patients with locally recurrent disease. Patients who completely responded to PDT had a median overall survival (OS) of 50 months, which was significantly longer (p < 0.003) than that of patients not responding to PDT. Toxicity was minimal; we recorded three cases of esophageal stenosis (7%) and one case of tracheo-esophageal fistula (2.5%) after combined PDT and radiotherapy. CONCLUSION: PDT is an effective regimen for early esophageal cancer, giving a CR rate of about 40%, long-term local control and favorable overall survival. Additional radiotherapy in cases of incomplete response to PDT is effective and potentially curative in another 45% of cases.

Concurrent hypofractionated radiotherapy and 5-Fluorouracil for advanced sarcomas of the bone.

Purpose. 5-Fluorouracil (5-FU) has shown radiosensitizing properties in vitro. This paper reports the effects of radiotherapy and concomitant intravenous 5-FU radiosensitization in the treatment of advanced bone sarcomas.Subjects/methods. Four patients with large inoperable bone sarcomas (three chondrosarcomas and one fibrosarcoma) were treated with hypofractionated radiotherapy and concomitant 5-FU bolus injection (300 mg m(-2)) before each fraction of radiotherapy. A radiation fraction of 5 Gy was given twice a week to a normalized total dose (alpha/beta=4 Gy) of 75 Gy.Results. The regimen was well tolerated, the main toxicity being grade I/II diarrhoea in two cases with pelvic irradiation. Treatment interruption for 1 week was necessary in two cases with pelvic disease but not in two patients treated for sarcoma of the extremities. A complete symptomatic relief was obtained in all cases immediately after the third to the fifth fraction and the median duration was 10 months. Computed tomography scan documented a partial response in 2/4 cases.Discussion. Hypofractionated radiotherapy combined with potential lethal damage inhibitors for bone sarcomas requires further investigation.

Hypofractionated radiotherapy with 5-fluorouracil radiosensitization for locally "far advanced" breast cancer.

Seventeen patients who had locally far-advanced breast cancer were treated with hypofractionated radiotherapy (4-5 Gy/fraction, twice a week) and concomitant 5-fluorouracil (5-FU 300 mg/m2 intravenously, 1 hour before every radiotherapy fraction). Fourteen of the seventeen patients had disease that was not responding to chemotherapy. Early toxicity was low and none developed grade III/IV toxicity. Two of the seventeen patients showed moist skin desquamation and four of seventeen had grade II anemia. Of eight patients who survived longer than 12 months, symptomatic breast fibrosis was observed in one (12%), asymptomatic pericarditis in one (12%) and symptomatic radiation pneumonitis in one (12%). Plexopathy and arm edema grade II were observed in one patient and two patients, respectively. Quality of life substantially improved. Complete response was documented in five of the seventeen patients (29%), with pathologic confirmation in three. Seven of the seventeen (41%) patients were considered to be partial responders, four (23%) had a minimal response, and one (6%) progressed during treatment. Local progression-free survival (1-24 months) was achieved in 12 of 17 patients. Four of the seventeen (23%) patients are alive, with no evidence of disease (local or distant) 8 to 24 months after radiotherapy. Hypofractionated chemoradiotherapy with 5-FU is an effective, convenient, and well-tolerated regimen for far-advanced breast tumors.

The impact of overall treatment time on the results of radiotherapy for nonsmall cell lung carcinoma.

PURPOSE: We evaluated the impact of overall treatment time on the disease-free survival (DFS) and local control after radiotherapy for nonsmall cell lung carcinoma. METHODS AND MATERIALS: One hundred fifty-three cases considered as responders to radiotherapy were retrospectively analyzed. Patients with Karnofsky status < 70, pretreated with chemotherapy and with pleural or pericardial effusion, were excluded from the analysis. Radiation dose homogenization was done with calculation of the normalized total dose without (NTD) and with time correction (NTD-T) for alpha/beta = 10 Gy. RESULTS: Kaplan-Meier curves for 2-year DFS showed that any analysis based on radiation dose can prove to be erroneous when the time factor is neglected. Although there was no difference between the 47-55 Gy and 56-64 Gy NTD groups, a log rank test revealed a strong difference (p < 0.0002) between NTD-T groups. No difference was observed for patients with mediastinal involvement. Logistic regression analysis showed a statistical association of dose on 2-year local progression-free probability for different time compartments. For those cases without mediastinal involvement, the daily dose lost because of treatment protraction beyond 20 days after the beginning of radiotherapy was estimated to 0.2 Gy/day. When all cases were considered together this was calculated to 0.45 Gy/day. CONCLUSION: Time factor should not be underestimated when evaluating the results of radiotherapy for nonsmall cell lung cancer. There is strong evidence that prolonged overall treatment time could be a major cause of the failure of radiotherapy to control the local disease.

Hypofractionated radiotherapy with concurrent 5-fluorouracil radiosensitisation for recurrent or locally advanced colorectal cancer. A phase II study.

In a pilot study we treated 19 patients suffering from recurrent or locally advanced inoperable colorectal cancer, with concurrent hypofractionated radiotherapy (4-5 Gy/fraction, 2 fractions per week) and 5-fluorouracil bolus, 1 hour before RT at doses of 300 mg/m2. For 16 patients treated with radical intent the Normalised Total Dose for alpha/beta = 10 Gy ranged between 56-74 Gy (median 62 Gy). The schedule used was very well tolerated. Moderate grade II haematological toxicity was observed in 11% of cases and diarrhoea grade II/III resulting in 2-4 weeks treatment delay was observed in 26% of cases. One case with bowel perforation and one with painful subcutaneous fibrosis was observed during 12-27 months of follow-up. Out of 16 patients treated with radical intent 4 (25%) showed complete response and the overall response rate was 56% (9/16). The one-year symptom-free survival was obtained in 11/16 (69%) radically treated patients. It is concluded that hypofractionated radiochemotherapy with 5-fluorouracil for recurrent or locally advanced colorectal cancer is an effective regimen and has acceptable acute and late toxicity. Further investigation is required.

Radiotherapy alone for non-small cell lung carcinoma. Five-year disease-free survival and patterns of failure.

One hundred and fifty-three patients with inoperable non-small cell lung cancer (NSCLC) treated with radiotherapy alone have been retrospectively analysed. Normalized Total Dose (NTD) as defined by Macejewski, TN-stage (AJC-system) and histology have been examined with respect to 5-year disease-free survival (DFS) and the patterns of failure so as to identify subgroups of patients that routinely should be treated with radical intent. The 5-year DFS for T1, 2-N0, 1 and T3-N0, 1 staged patients was 30% (7/23) and 25% (4/16) respectively when the tumor NTD (a/b = 10 Gy) was 56-64 Gy vs. 12% (5/41) and 0% (0/10) when the NTD was 48-55 Gy. This difference was statistically significant for the squamous cell histology group. The higher doses significantly altered the patterns of death in N0, 1 staged squamous cell carcinoma and adenocarcinoma patients. Forty-five percent (22/55) and 41% (12/29) of squamous cell and adenocarcinoma patients respectively, died from local relapse without evidence of distant metastases when NTD less tha 55 Gy were given vs. 21% (9/42) and 13% (2/15) when the NTD delivered was 56-64 Gy (p < 0.05). Although for N2, 3 staged patients or patients with direct extension of the tumor into the mediastinum death from local relapse occurred in 38% (10/26) of the high NTD treated patients vs. 51% (19/37) of the low-dose treated ones, the difference was not statistically significant. It is concluded that NSCLC patients should not à priori be considered as non-radiocurable. At least 30% of the patients with early local stages can be long-term disease-free survivors with radiation NTD up to 60 Gy and better results are to be expected with higher doses. Advanced T-stage without mediastinal involvement should be treated with radical intent since a high NTD could give cure rates of over 25%. The disappointing results for patients with mediastinal disease could perhaps be attributed to the low NTD delivered. For patients with good performance status, hyperfractionated regimens delivering high tumor doses should be tested and chemotherapy should be adapted to these radiation treatment schedules.
