Proposal for a shared definition of « primary healthcare » by health professionals: A national cross-sectional survey.

Introduction: Forty years passed between the two most important definitions of primary health care from Alma Alta Conference in 1978 to WHO's definition in 2018. Since then, reforms of healthcare systems, changes in ambulatory sector and COVID 19, have created a need for reinterpretations and redefinition of primary healthcare. The primary objective of the study was to precise the definitions and the representations of primary healthcare by healthcare professionals.

Basal cell carcinoma of the face: surgery or radiotherapy? Results of a randomized study.

Basal cell carcinomas (BCCs) are very frequent cutaneous cancers, often located on the face. Cure rates with surgery and radiotherapy are high, but these treatments have never been compared prospectively. A randomized trial was initiated in 1982 to compare surgery and radiotherapy in the treatment of primary BCC of the face measuring less than 4 cm.

Melanoma in childhood: an EORTC-MCG multicenter study on the clinico-pathological aspects.

Melanoma in children is rare. Nevertheless, it is imperative that clinicians be aware that melanoma does occur in childhood. Yet there is very little information available on the clinico-pathologic variations, and the prognostic parameters of melanoma in children.

Comparison between familial and nonfamilial melanoma in France.

Background And Design: Five percent to 10% of cutaneous malignant melanomas (CMMs) occur in a familial setting. Clinical, epidemiologic, and genetic studies of familial CMM in different regions of the world have led to various results. To assess the characteristics of familial CMM in France, the clinical, histologic, and epidemiologic characteristics of 295 patients with CMM were recorded, and a comprehensive familial investigation was performed for each case.

Prognostic value of neural invasion in rectal carcinoma: a multivariate analysis on 339 patients with curative resection.

To determine whether neural invasion or other clinico-pathological factors are prognostic, we performed a retrospective study on 339 rectal carcinomas. The overall 5-year survival was 62%. In the multivariate analysis, age over 60 years, a distance from the anal verge of less than 6 cm, the number of positive lymph nodes, neural invasion and tumour penetration were found to be prognostic.

Tumour oxygenation, radiosensitivity, and necrosis before and/or after nicotinamide, carbogen and perflubron emulsion administration.

Hypoxia is one of the factors involved in tumour resistance to radiotherapy. One way to improve tumour oxygenation is to use oxygen carriers such as perflubron emulsion plus carbogen or vasoactive drugs such as nicotinamide. The perflubron emulsion and carbogen act mainly on hypoxia caused by limited diffusion of oxygen; nicotinamide acts mainly on acute hypoxia.

Melanoma arising de novo in childhood: experience of the Gustave-Roussy Institute.

Between January 1956 and December 1990, 17 patients younger than 17 years with available pathological screens of de novo cutaneous melanoma, and with no other risk factors (xeroderma pigmentosum, giant congenital naevi, congenital melanoma or a proven family history of dysplastic naevus syndrome) were seen at the Gustave-Roussy Institute. The median age was 9 years and 9 months (range 2 years and 3 months-16 years and 9 months). The primary disease was located in the lower extremities in 10 cases, the trunk in five cases, and the upper extremities or head and neck in one case.

Borderline and malignant serous tumor arising in pelvic lymph nodes: evidence of origin in benign glandular inclusions.

This report describes two cases of malignant serous cancers with areas of borderline malignancy, which appear to have arisen within benign glandular inclusions of coelomic origin in pelvic or para-aortic lymph nodes. The patients were 44 and 62 years of age. In both cases the nodes contained benign glandular inclusions lined by a single layer of epithelium which resembled that of tubal epithelium.

Carcinomas of the colon with multidirectional differentiation. Report of two cases and review of the literature.

Two cases of colonic carcinomas with multidirectional differentiation are presented. Both tumors showed light microscopic and immunohistochemical evidence of areas of adenocarcinomatous, squamous cell carcinomatous, and neuroendocrine differentiation. Only six similar cases have been previously reported.

[Classification of ovarian tumors based on embryogenesis].

This paper studies gonadal differentiation into the ovary from the earliest interaction between germ cells and somatic cells in the developing urogenital ridge up to the formation of primordial follicles. Granulosa cells appear to be derived from the breaking down of the cordlike arrangement of epithelial cells resulting from proliferation of surface coelomic mesothelium. Thecal cells arise from mesenchymal progenitors cells in the ovarian stroma.

Identification of genes overexpressed in tumors through preferential expression screening in trophoblasts.

Early trophoblastic cells share several features with neoplastic cells. Based on that observation, we attempted to identify genes overexpressed in tumors by analyzing genes preferentially expressed in trophoblasts. A subtracted library enriched in complementary DNA from early cytotrophoblasts was constructed, and the expression level of selected recombinants was analyzed on a large panel of normal and tumor tissues.

[Cervical cancer in the young woman].

Uterine cervix carcinoma is considered by some authors to carry a poor prognosis in young patients (< 35 years of age). From 10 years, many series have been published with divergent conclusions. However, a group of patients with poor prognosis could be individualized; age < 30 years, locally aggressive tumour, poorly differentiated, nodal involvement, amplification of c-Myc proto-oncogene.

A comparison of early effects with two dose rates in brachytherapy of cervix carcinoma in a prospective randomised trial.

This phase III randomised trial examined the early effects of two low dose rates (0.38 and 0.73 Gy/h) in brachytherapy of stage I and IIp cervical cancer patients.

Experimental study of balloon-expandable metallic vena caval stents in rabbits.

Purpose: The reactivity and patency of balloon-expandable Strecker stents were determined in the superior vena cava (SVC) and inferior vena cava (IVC) of rabbits.

Materials And Methods: One stent was placed in each of 24 rabbits; 15 were placed in the SVC and nine in the IVC. The duration of stent placement varied between 3 days and 15 months.

[Cutaneous malignant melanoma in New Caledonia (South Pacific) 1973-1991. A study of 97 cases].

The Cancer Registries have been operational in the South Pacific since 1958 (Papua New Guinea), Fiji (1965) and New Caledonia (1977) and complete cancer incidence rates are available, based on histologic data. We studied 97 melanomas, histologically confirmed, which were diagnosed in New Caledonia from 1973 to 1991. New Caledonia is located in the same latitude as Queensland in Australia, known for having the highest incidence of melanoma in the world.

Relationship between the melanin content of a human melanoma cell line and its radiosensitivity and uptake of pimonidazole.

The intra-cellular uptake of the weakly basic radiosensitiser pimonidazole (PIMO) was determined as a function of the pigmentation of Na11+ human melanotic melanoma cells in vitro. Two experimental conditions were considered: exponentially growing cells (Exp.) and plateau-phase cells (PI.

[Benign glandular inclusions in inguinal and abdominopelvic lymph nodes in gynecologic pathology].

From 4 cases recently seen at the Institut Gustave-Roussy, this report describes the pathological and evolutive features of benign glandular inclusions in inguinal, pelvic or abdominal lymph nodes. These lesions are defined by the presence of tubular formations in lymph nodes, lined by a single layer of epithelium which is cuboidal or columnar and resembled that of tubal epithelium with ciliated, secretory and intercalary cells. In most cases, benign glandular inclusions in lymph nodes still quiescent.

Ovarian dysgerminoma metastatic to the breast.

A 16-year-old girl underwent a right salpingo-oophorectomy for a pure dysgerminoma limited to the right ovary. One month later, she developed a right pelvic mass along with abdominal lymphadenopathies, peritoneal carcinomatosis, left breast mass, and left axillary node. Cytology of the breast mass was suggestive of a pure dysgerminoma.

Combined radiotherapy and surgery: local control and complications in early carcinoma of the uterine cervix--the Villejuif experience, 1975-1984.

From January 1975 to December 1984, 441 patients were treated by combined radiotherapy and surgery at the Institut Gustave Roussy (IGR) for Stage IB (288) and II (proximal) (103) carcinoma of the uterine cervix. Standard treatment consisted of pre-operative utero-vaginal brachytherapy (60 Gy) using a mould technique followed by a colpo-hysterectomy and external iliac lymphadenectomy. Overall 5 year actuarial survival for the whole population was 87% and disease-free survival 85%.

Combined radio-surgical treatment in early invasive cervix carcinoma according to prognostic factors. Experience of the Gustave-Roussy Institute.

In the Gustave-Roussy Institute the standard protocol of limited stages (IB, proximal II) of cervix carcinoma, combines endocavitary brachytherapy (low dose rate) and surgery (BSOH + lymphadenectomy) are eventually followed by external beam irradiation. According to age of patients and to prognostic factors adaptations of this combined treatment are discussed: young patient (40 years) with small tumor, large volume of primary tumor (4 cm), lymphatic node involvement. Analysis of the results in 2 series of patients entirely treated at the Gustave-Roussy Institute: survival, local control, metastases, complications.
