[High fetal irradiation: about one pregnant woman receiving infradiaphragmatic radiotherapy for Hodgkin lymphoma]. / Irradiation foetale élevée: à propos d'une femme dont la grossesse était méconnue irradiée en sous-diaphragmatique pour un lymphome hodgkinien.

We report the case of a 19-year-old young woman for whom was discovered a pregnancy at the end of the irradiation for a Hodgkin lymphoma (stage IV bone Bb), initially treated by chemotherapy. The radiotherapy delivered 36 Gy in infra-diaphragmatic volumes (lombo-aortic, spleen, L5), beginning in a pregnant patient for less than 4 amenorrhea weeks. The calculated received fetal dose (literature data, measurement with software TPS, measurement on phantom) is high: it's between 2.8 and 5 Gy. With a current follow-up of 4 years since the radiotherapy's end, the patient is in complete remission and her child presents with a normal development for the age, in spite of the infradiaphragmatic irradiation.

[Curative salvage treatment of mediastinal and pleuropulmonar metastatis from anal canal cancer]. / Chimioradiothérapie de rattrapage pour métastases médiastinales et pleuropulmonaires d'un cancer du canal anal.

This case report presents a 57 years-old woman treated for a squamous cell carcinoma of the anal canal by radiochemotherapy and brachytherapy. The particularity of this case lays on the fact that she presented a mediastinal and pleural metastatic evolution three years later, which was also treated by radiochemotherapy, leading to a complete remission of 50 months. This observation is interesting for its curative treatment in metastatic cancer of the anal canal. It also illustrates the radiosensibility of anal canal cancers, including metastatic situations, and raises the contribution of PET-scanner to evaluate the response to treatment and detect a recurrence.
