Breast phantom for comparison X-ray and polarimetric optical tomography imaging.

Breast phantom made as combination of paraffin and INTRALIPID™ was tested by use of X-ray classical computed tomography and polarimetric optical tomography. The INTRALIPID™ is a liquid commonly used for simulation breast tissues optical properties but it is useless as X-ray phantom. During our tests we have observed that X-ray tomography allows to recognize a proper placement of INTRALIPID™ inclusions inside paraffin medium but we cannot distinguish density of INTRALIPID™ within each inclusions. On the other hand the polarimetric optical tomography allows to distinguish density of INTRALIPID™ (0%, 10%, 20%) in inclusions but with relatively low accuracy of their placement.

[Chondrosarcoma of the small pelvis imitating an ovarian tumor]. / Chrzestniakomiesak miednicy mniejszej imitujacy guz jajnika.

The authors present diagnostic-therapeutic record concerning chondrosarcoma-tumor in 41-year-old women operated on ovary-tumor. They point out the rareness of chondrosarcoma within pelvis, the diagnostic and therapeutic difficulties and relapses into illness after radical remove of tumour without pelvis bones resection.

[Identification of a limited form of small cell lung cancer among 103 patients pre-selected for chemotherapy combined with surgery]. / Wyodrebnienie postaci ograniczonej drobnokomórkowego raka pluca w grupie 103 chorych wstepnie wyselekcjonowanych do chemioterapii w skojarzeniu z chirurgia.

Between Nov. 1981 and Nov. 1987 103 patients preselected for chemotherapy combined with surgery, therefore with local extension within homolateral mediastinal lymph nodes, with no signs of remote metastases, PS greater than or equal to 70, with no contraindication for resectional surgery including pneumonectomy, no diabetes, no prior treatment underwent first staging. Staging included: case history, physical examination, full blood count, biochemical tests (alkaline phosphatase, SGOT, GGTP, LDH), CEA, X-ray assessment including CT scan of the chest, bronchoscopy, peritoneoscopy, liver scan (US was not routinely used at the beginning), bilateral bone marrow trephine biopsy, and bone scan. Staging was discontinued when secondaries were detected in one, the more so as in two organs or systems (25 pts), and/or bronchoscopic contraindication for thoracotomy (11 pts), and this group of patients was out of the study. To 67 patients chemotherapy was given and after 3 courses these patients were reevaluated. In 21 patients PD, NC or CR was found. Forty six patients with PR underwent supplementary staging procedures: CT of the brain, CT of the upper retroperitoneal space and liver. Metastatic sites were found in 7 patients. Limited disease was identified in 39 patients. Limited-stage disease can be determined only after exclusion of extensive disease on the ground of: case history, physical assessment, X-ray of the chest (PA + lateral) + CT chest scan, bronchoscopy with biopsy or cytology, and outside the chest: 1. bone marrow trephbine biopsy and bone scan--bone marrow and skeleton, 2. CT head scan--brain, 3. CT abdominal scan--upper retroperitoneal space and liver.
