RESUMO

PURPOSE: To analyse whether psychological demands and decision latitude measured on individual and work-unit level were related to prescription of antihypertensive medication. METHODS: A total of 3,421 women and 897 men within 388 small work units completed a questionnaire concerning psychological working conditions according to the job strain model. Mean levels of psychological demands and decision latitude were computed for each work unit to obtain exposure measures that were less influenced by reporting bias. Dispensed antihypertensive medication prescriptions were identified in The Danish National Prescription Registry. Odds ratios (OR) comparing the highest and lowest third of the population at individual and work-unit level, respectively, were estimated by multilevel logistic regression adjusted for confounders. Psychological demands and decision latitude were tested for interaction. Supplementary analyses of 21 months follow-up were conducted. RESULTS: Among women, increasing psychological demands at individual (adjusted OR 1.54; 95 % CI 1.02-2.33) and work-unit level (adjusted OR 1.41; 95 % CI 1.04-1.90) was significantly associated with purchase of antihypertensive medication. No significant association was found for decision latitude. Follow-up results supported an association with psychological demands but they were not significant. All results for men showed no association. Psychological demands and decision latitude did not interact. CONCLUSION: High psychological work demands were associated with the purchase of prescribed antihypertensive medication among women. This effect was present on both the work-unit and the individual level. Among men there were no associations. The lack of interaction between psychological demands and decision latitude did not support the job strain model.

RESUMO

OBJECTIVES: To evaluate dental maturity in the mandibular canine/premolar and molar innervation fields in children with agenesis of the 2nd mandibular premolar and to associate these findings with normal control material. SETTING AND SAMPLE POPULATION: Department of Orthodontics, Institute of Odontology, University of Copenhagen. Eighty-three panoramic radiographs (27 girls and 31 boys with agenesis of one mandibular 2nd premolar and 17 girls and eight boys with agenesis of both mandibular 2nd premolars) represented all mandibular second premolar agenesis cases from a material of 2847 radiographs. MATERIAL AND METHODS: On each radiograph, dental maturity of all available mandibular premolars, canines and 2nd molars was evaluated and categorized in maturity stages according to Haavikko whose material served as control material. Descriptive statistics given by sample mean, standard deviation and range for each tooth stratified by gender and agenesis. Ninety-five percentage confidence limits and T-statistics were used. p-values <5% were considered significant. RESULTS: In unilateral agenesis, the canines are specifically delayed in both girls and boys, with a larger delay in girls (p=0.009). The second molar is not delayed in boys (p=0.98) but is in girls (p=0.04). The differences in delay for the canine compared to the second molar are significant for both girls and boys. The results show a considerable delay in tooth maturation within the canine/premolar innervation field predominantly in girls. The 2nd molar is delayed in girls but not in boys.

RESUMO

No standard treatment is established for patients with advanced soft tissue sarcoma after previous chemotherapy with anthracyclines and ifosfamide, given either in combination or sequentially. Exatecan (DX-8951f) is a totally synthetic analogue of the topoisomerase I-inhibitor camptothecin, which was synthesised to impart increased aqueous solubility, greater tumour efficacy, and less toxicity than camptothecin itself, topotecan or irinotecan. Since some activity against soft tissue sarcomas, especially leiomyosarcomas, has been reported for topoisomerase I-inhibitors, a study with a new and more potent agent seemed justified. We report on a prospective multicentre phase II study of Exatecan in adult soft tissue sarcomas failing 1 or 2 lines of chemotherapy in advanced phase, performed within the STBSG of EORTC. Thirty-nine patients (16 leiomyosarcomas and 23 other histologies) were included in two independent strata and received a total of 141 cycles (median 2). Median age was 61 years, range 25-76. Exatecan was given as i.v. infusion over 30 min at a dose of 0.5mg/m2 every day for five consecutive days, repeated every 21 days. Seventy-four percentage of cycles could be given without dose or schedule modification. The main toxicity was haematotoxicity with grade 3/4 neutropenia in 49%, grade 3/4 thrombocytopenia in 23%, and grade 3/4 anaemia in 15% of patients, respectively. Non-haematological toxicity consisted mainly of grade 2/3 dyspnoea in 36% of patients and grade 2/3 fatigue in 28%. One treatment-related toxic death due to septic shock was reported. Best overall response was no change with 60% in the leiomyosarcoma group and 53% in the non-leiomysarcoma group, respectively. The 3 months progression-free survival estimates are 56% for leiomysarcomas and 26% for other histologies, respectively. Using a two-step statistical design, the trial was stopped after the first step in both strata, due to lack of activity. In pretreated soft tissue sarcoma patients, Exatecan is well tolerated but does not achieve any objective responses. However, with respect to progression-free survival, Exatecan did show some activity in leiomyosarcomas.

RESUMO

This phase I study evaluated the toxicity of first-line combined pegylated liposomal doxorubicin (Caelyx) and ifosfamide in patients with advanced and/or metastatic soft tissue sarcomas. Five dose levels (L) were studied: Caelyx 30 mg/m2 (L1-4) or 40 mg/m2 (L5) 1-h infusion d 1 q 3 weeks + ifosfamide and mesna at X g/m2/4 h d 1-3 q 3 weeks at five doses: L1: X = 1.7 g; L2: X = 2 g; L3: X = 2.5 g; L4 and L5: X = 3 g. Cohorts of 3 patients were entered at each level unless a dose-limiting toxicity (DLT) occurred. In case of DLT in 1 of 3 patients a new cohort was added. Toxicity was evaluated by Common Toxicity Criteria (CTC). A total of 28 patients was included: 4 at dose L1, 8 at L2, 3 at L3, 6 at L4, and 7 at L5. Median age was 60 years (range 29-69 years). Male/female ratio was 12/16. Seventy-five percent of patients had a performance status of 1.0 and 36% had leiomyosarcomas. No DLT was observed at dose L1-4. Six patients developed a DLT at dose L5, and thus the recommended dose is level 4 (i.e. Caelyx 30 mg/m2/1 h d 1+ifosfamide at 3 g/m2/4 h d 1-3 q 3 weeks). Few haematological and biochemical events were observed and the principal toxicities were granulocytopaenia and leucopaenia. Five patients discontinued therapy because of toxicity, 4 of them at dose level 5. Non-haematological toxicities > grade 2 were also few. Palmar-plantar erythrodysesthesia (PPE) > grade 1 was not seen. Two patients obtained partial response (PR) and 13 stable disease (SD). Median overall survival (OS) was 333 d and median progression-free survival (PFS) 174 d. In conclusion, this seems to be a feasible combination in patients with advanced soft tissue sarcomas, allowing ifosfamide to be given in a dosage similar to that used when given alone. The recommended dose for future studies is Caelyx 30 mg/m2/1 h d 1+ifosfamide 3 g/m2/4 h d 1-3 q 3 weeks.

RESUMO

Schwannoma of the nasal cavity or the sinuses is a rare condition. We report a small series of five consecutive patients; three males and two females, age range 22-81 years, all Caucasian. Symptoms were typically non-specific, and the tumours were often quite large when diagnosed, being locally infiltrating and even destructive. Histologically, the tumours were remarkable by sparse occurrence of Antoni type B areas and lack of encapsulation. Four cases were benign; however, one case of melanotic schwannoma, exhibited malignant transformation. Two of the patients had intracranial involvement, but with an intact dura. All tumours were treated surgically; only the malignant case received adjuvant radiotherapy. Patients were followed from five months to 15 years, with a median of 57 months. The benign cases have so far shown good prognosis without recurrences; however, in the case of the melanotic schwannoma a fatal malignant transformation was seen 13 years after initial diagnosis. On the basis of our review early detection and complete surgical removal is recommended.

RESUMO

OBJECTIVE: The aim of this study was to report our experience with malignant and borderline soft tissue tumours (STS) of the head and neck region in the period 1977-2000. DESIGN: Retrospective case study including new evaluation of histological specimens. SETTING: Tertiary centre, single centre. PARTICIPANTS: Review of patient's records and new evaluation of pathological specimens were made for 66 patients. After evaluation only 36 patients (26 men and 10 women) still met present criteria for a STS in head and neck in adults. RESULTS: The original histological diagnosis was changed in 27 (41%) of the 66 patients with a primary diagnosis of sarcoma. After review the most common histological diagnoses were leiomyosarcoma (5) and rhabdomyosarcoma (5). Overall 5-year survival rate was 60%. Overall 5-year disease-free survival rate was 44%. The study showed that both tumour grade and surgical margin had a statistically significant impact on survival. No relation was found between survival and tumour size or age. CONCLUSION: The grave prognosis especially for high-grade tumours emphasizes the need for improved treatment strategies. Furthermore, conclusions from older studies concerning prognosis may be obsolete as approximately 40% of tumours previously diagnosed as sarcomas may be invalid by present day standards.

RESUMO

In order to analyse the impact of modern sarcoma classification criteria, pathological material from 281 extremity soft-tissue sarcomas (STS) was reviewed. The cases were originally diagnosed between 1972 and 1994, and the most frequent diagnoses then were malignant fibrous histiocytoma (MFH) (26%), liposarcoma (21%), fibrosarcoma (11%), and leiomyosarcoma (10%). After reclassification, the proportions had changed significantly, with the largest group now being leiomyosarcomas (20%), liposarcomas (17%), synovial sarcomas (14%), and sarcomas "not otherwise specified" (NOS) (11%). The original diagnosis was changed in 57% of the cases; in particular, the number of fibrosarcomas was reduced from 32 to 6, and MFHs from 72 to 2, with 22 renamed as myxofibrosarcomas; 20 (7%) were found not to be sarcomas. The main reasons for these results are the recent advances in immunohistochemistry (IHC) together with changes in nomenclature. The findings have obvious implications, in particular for retrospective research.

RESUMO

AIMS: Ossifying fibromyxoid tumour is a rare lesion that generally occurs in the soft tissues of proximal limbs/girdle, or head and neck. Histologically, it usually consists of bland, mitotically inactive, S100+ cells in a fibromyxoid matrix with a characteristic peripheral ossification. However, we present two cases that deviated from this pattern. MATERIAL AND METHODS: One tumour, which was removed from the axilla of a 55-year-old female, was unusual in its large size (120 mm in diameter) and in its restriction of bone formation to its central zones. The other tumour, which occurred in a 62-year-old female, was remarkable in its acral location on the hand and high mitotic activity (four mitoses per high-power field). These features caused concern and follow-up of the patients was recommended. So far there have been no recurrences (25 and 18 months after surgery, respectively). An additional previously undescribed feature was the presence of fibronexus-like structures by electron microscopy in the second case. However, a myofibroblastic phenotype was not supported by the immunohistochemical findings. CONCLUSION: Though a distinct entity, ossifying fibromyxoid tumour may exhibit a wider clinicopathological spectrum than generally recognized.

RESUMO

PURPOSE: To describe a patient with liposarcoma metastatic to the left orbit. METHODS: A 72-year-old man was admitted with diplopia and proptosis of the left eye. Previously, a retroperitoneal liposarcoma had been surgically removed followed by postoperative radiation. Visual acuity was normal. There was proptosis of the left eye, increased retrobulbar resistance and reduced mobility. Trans-septal orbital biopsies showed liposarcoma. The patient was initially treated with prednisolone and later received radio- and chemotherapy. Despite treatment he lost vision of the left eye and died a few months later. RESULTS: Histological examination of the orbital tumor revealed a spindle-cell liposarcoma similar to the primary tumor of the retroperitoneum. CONCLUSIONS: Liposarcoma metastatic to the orbit is rare, but should be suspected in a patient with proptosis caused by a space-occupying lesion and a history of liposarcoma.

RESUMO

Purpose. Doxorubicin (dox) still appears to be one of the most active drugs in the treatment of soft tissue sarcomas. However, treatment duration is limited due to cumulative cardiotoxicity. A number of small studies from single institutions have suggested activity of other analogues. In two studies the EORTC STBSG tested whether epirubicin (epi) is an alternative to standard dose dox in the treatment of chemonaive patients with advanced soft tissue sarcoma. The present report gives the final results of these studies.Patients/Methods. In the first study 210 patients were randomized to receive either dox or epi both at a dose of 75 mg/m(2) given as bolus injection at 3-week intervals. In the second study 334 patients were randomized to dox 75 mg/m(2), epi 150 mg/m(2) or epi 50 mg/m(2) days 1-3, all given as bolus injection at 3-week intervals.Results. In the first study no differences in median survival and duration of response were found. Of 167 evaluable patients the response rate was slightly in favour of dox (23% vs 18%) but at the expense of more toxicity.These data could suggest that increasing the epi dose may lead to a greater antineoplastic effect with acceptable toxicity. In the second study 15% of 314 evaluable patients had an objective tumour response. There were no differences between the three groups with regard to response rate, progression-free and overall survival, but both dose schedules of epi were more myelotoxic than dox.Conclusion. Regardless of schedule and dose, epi is not superior to dox in the treatment of patients with advanced soft tissue sarcomas. In addition, the results illustrate that the data from small studies of single institutions should always be confirmed by large multi-institutional studies before being taken for granted.

RESUMO

The activity and toxicity of single-agent standard-dose doxorubicin were compared with that of two schedules of high-dose epirubicin. A total of 334 chemonaive patients with histologically confirmed advanced soft-tissue sarcomas received (A) doxorubicin 75 mg m(-2) on day 1 (112 patients), (B) epirubicin 150 mg m(-2) on day 1 (111 patients) or (C) epirubicin 50 mg m(-2) day(-1) on days 1, 2 and 3 (111 patients); all given as bolus injection at 3-week intervals. A median of four treatment cycles was given. Median age was 52 years (19-70 years) and performance score 1 (0-2). Of 314 evaluable patients, 45 (14%) had an objective tumour response (eight complete response, 35 partial response). There were no differences among the three groups. Median time to progression for groups A, B and C was 16, 14 and 12 weeks, and median survival 45, 47 and 45 weeks respectively. Neither progression-free (P = 0.93) nor overall survival (P = 0.89) differed among the three groups. After the first cycle of therapy, two patients died of infection and one owing to cardiovascular disease, all on epirubicin. Both dose schedules of epirubicin were more myelotoxic than doxorubicin. Cardiotoxicity (> or = grade 3) occurred in 1%, 0% and 2% respectively. Regardless of the schedule, high-dose epirubicin is not a preferred alternative to standard-dose doxorubicin in the treatment of patients with advanced soft-tissue sarcomas.

RESUMO

The differential diagnosis between primary endocervical adenocarcinoma and adenocarcinoma originating in the endometrium may in some cases be difficult. The two cancer types have a different genesis, with human papillomavirus (HPV) as an important causal factor in the development of primary cervical carcinoma. In this study, the paraffin-embedded cervical tissues from 23 patients with stage II endometrial carcinoma and from 50 patients with primary cervical adenocarcinoma were examined for HPV DNA of types 16, 18, and 33. HPV DNA was demonstrated in 70% of the primary endocervical adenocarcinomas and in none of the endometrial carcinomas. It is concluded that HPV detection may be useful in the differential diagnosis of some cases of cervical and endometrial adenocarcinoma.

RESUMO

Purpose. In an attempt to identify clinical and histopathological factors of prognostic importance in chondrosarcomas, 115 cases of malignant and borderline chondromatous tumours were reviewed.Patients/methods. Histopathological features tested for prognostic information as well as reproducibility included cellularity, nuclear pleomorphism, multinucleated cells, mitotic activity and grade. Eleven patients had a biopsy only, and a short survival (median 2.0 years); these were excluded from further analysis. The remaining 104 patients who had received intended curative treatment had a median survival of 14.7 years.Results. In univariate analysis, tumour size, extra-compartmental growth, surgical margin and sex were significantly correlated to recurrence-free survival (RFS); sex was marginally significant while age, site and pathological parameters were not significant. Overall survival (OAS) was likewise found to be independent of pathological features as well as site, size and surgical margin; but age, sex and extra-compartmental growth were statistically significant. However, when the same parameters were entered into a stepwise Cox (multivariate) analysis, only surgical margin, cellularity and pleomorphism were significantly related to RFS; margin, grade, pleomorphism and age to OAS. Overall inter-observer agreement on grade was relatively low: 0.54, with a Kappa value of 0.32. It was not better for the other histological parameters, with the exception of the mitotic count. However, acceptable values were achieved when the material was divided into low-grade (grade I and below) vs high-grade (grade II and III) lesions: overall agreement 0.79, Kappa 0.56.Discussion. Although the grading of chondrosarcomas is in need of improvement, its replacement by semiquantitative evaluation of individual histopathological parameters as performed in this study offers no advantage. Among the clinical parameters, only the adequacy of the surgical treatment and the patient's age appear to be important.

RESUMO

In 143 patients with vulvar carcinoma (76 cases) or vulvar intraepithelial neoplasia (VIN III, 67 cases), cervical cancer or cervical intraepithelial neoplasia CIN III lesions developed in 39 patients (27%) at some time during their life. In patients with classic keratinizing squamous cell carcinoma (KSC) of the vulva, cervical neoplasia developed in only one of 51 (2%), whereas the frequency was 10 of 25 (40%) in patients with vulvar carcinoma of the basaloid or warty type and 28 of 67 (42%) in patients with VIN III lesions. The original, paraffin-embedded surgical specimens were examined by polymerase chain reaction and type-specific molecular hybridization for human papillomavirus (HPV) DNA of the types 6, 11, 16, 18, and 33. DNA of the oncogenic types HPV 16 or HPV 33 was found in 4% of the KSCs, in 84% of the basaloid or warty carcinomas, in 90% of VIN III lesions, and in 89% of the cervical lesions. The same HPV type was found in both lesions in 81% of the patients with double primary tumors. The results support the concept that VIN III and a subgroup of vulvar carcinomas are HPV-related lesions, that they are frequently associated with another HPV-related genital primary tumor, and that these multiprimary tumors are secondary to an HPV infection involving the entire genital tract.

RESUMO

Six cases of elastofibroma located in the subscapular region are reported. The age of the patients ranged from 45 to 71 years (mean 59.5 years). In three cases the symptoms were posterior shoulder pain with arm motion, and one of these also had a snapping scapula. Two cases had tumor prominence as the only symptom, and in one case the tumor was found accidentally while thoracotomy was being performed. On magnetic resonance imaging a nonencapsulated soft-tissue mass closely related to the thoracic wall and elevating the scapula was identified. At surgery the tumor was densely adherent to the periosteum of the ribs and the external fascia of the rib cage, and peripherally it proceeded into the loose connective tissue of the subscapular space. Local excision was performed. At follow-up 1 to 8 years after surgery no recurrence was observed, and all patients with painful lesions had complete relief of pain.

RESUMO

PURPOSE: To investigate the course of chondrosarcoma in relation to radiographic and histopathologic findings. MATERIAL AND METHODS: 49 consecutive patients seen during an 11-year-period were analysed, including re-evaluation of their radiographic and histopathologic material. RESULTS: Forty-two patients had radiographic changes typical for cartilaginous tumours, in 37 with malignant stigmata. Seven patients had malignant changes not typical for chondrosarcoma. By histopathologic grading 16 patients had grade I, 17 grade II and 16 grade III tumours. Six of the grade II-III tumours were histopathologic variants (mesenchymal, dedifferentiated or myxoid chondrosarcomas). Surgical removal of the tumour was performed in 42 patients, 41 of whom were followed up for 0.4-11.4 years (median 3.8 years). Local recurrence occurred in 7 patients, and 11 patients developed metastases. Ten patients, 4 with local recurrence and metastases, and 6 with metastases only were dead at the end of the follow-up. The actuarial 5-year overall survival rate was 64%. The occurrence of local recurrence, metastases and death was found to be related to the histopathologic grades II and III. Atypical radiographic features only occurred in grade II-III tumours and were related to metastases and death, but not to local recurrence. CONCLUSION: Atypical radiographic findings were related to high-grade malignancy and poor prognosis.

RESUMO

The polymerase chain reaction (PCR) was used to detect human papillomavirus (HPV) type 16 DNA in cervical swabs from 37 patients with HPV 16-harboring cervical lesions (15 carcinomas and 22 cervical intraepithelial neoplasias). Primers amplifying a sequence of the human beta-globin genome were used for internal control together with the HPV 16-specific primers. The cell samples were prepared for PCR analysis by two different methods: either by phenol/chloroform extraction or by boiling in the presence of a chelating agent. HPV 16 DNA was found in 27 swabs. The detection rates were identical with both methods of preparation. Four of the 10 false-negative swabs contained too little DNA to permit amplification with the genomic primers. Excluding these insufficient samples, the detection rate was 82%. Reasons for false-negative results may include low cell numbers or failure to obtain cells representative of the underlying lesion. In conclusion, the PCR offers a satisfactory method of HPV detection in cervical swabs. Cell preparation can be restricted to simple boiling with a chelating agent. For optimal results, samples containing less than 2 x 10(4) cells should be discarded, and genomic primers should be used for internal control.

RESUMO

The vulvectomy specimens of 78 patients with vulvar squamous cell carcinoma were reviewed and examined for human papillomavirus (HPV) types 6, 11, 16, 18, and 33 by the polymerase chain reaction technique. The tumors were classified as keratinizing squamous cell carcinoma (KSC), as warty carcinoma (WC), and as basaloid carcinoma (BC). DNA of HPV types 16 and 33 was found in 2/51 KSC, in 12/17 WC, and in 10/10 BC. HPV types 6, 11, and 18 were not detected. Patients with WC and BC were younger, and 78% had VIN III lesions adjacent to the carcinoma. Patients with KSC were older and had a high incidence of dystrophic lesions, including lichen sclerosus, adjacent to the tumor. None of the KSC showed adjacent VIN III. In conclusion, vulvar carcinoma segregates into two categories, of which KSC seems to be the classic type, only rarely associated with HPV infection, and mostly affecting older women; WC and BC constitute an HPV-related subgroup of tumors occurring in younger patients and are associated with VIN III lesions from which they may emerge.
