Bone involvement by adenocarcinoma of the uterine cervix: a rare entity.

BACKGROUND: Adenocarcinoma is the second most frequent cancer of the uterine cervix after squamous carcinoma, and the most frequent histotype is the mucinous one. Endo-cervical adenocarcinoma accounts for about 10-30% of all cervical cancers and clinically the lesion can be asymptomatic or, more frequently, presenting with anomalous bleeding and/or vaginal discharge. CASE REPORT: A 41-year-old woman with a diagnosis of adenocarcinoma of the uterine cervix was subjected to chemotherapy after radical surgery. During the follow-up, the patient underwent a Positron Emission Tomography integrated with Computed Tomography and pelvic Magnetic Resonance, which showed rapid and diffuse disease progression from the site of the lesion to the pelvic bones. CONCLUSIONS: Bone involvement in patients with cervical cancer, being a rare event, is significant since it greatly reduces life expectancy. The majority of metastatic bone lesions in cervical cancer seem to be of osteolytic nature. In our patient, Positron Emission Tomography integrated with Computed Tomography and Magnetic Resonance were the imaging methods used during the follow-up and both techniques clearly showed diffuse and rapid tumour spread to the bones.

Idiopathic scrotal hematoma simulating a testicular torsion, in association with cryptorchidism: US findings.

BACKGROUND: An acute scrotum concerns endoscrotal organs (testicles, spermatic cord, tunica vaginalis) and is characterized by pain, swelling and hyperemia of the hemi-scrotum. It represents one of the most common surgical emergencies in children often caused by testicular torsion; the diagnosis is mostly clinical but must be supported by ultrasonographic examination of the scrotal region in association with a colour Doppler study of the spermatic cord vessels and glandular parenchyma. An idiopathic scrotal hematoma is a very rare condition that can simulate it. CASE REPORT: A 3-day-old full-term baby, otherwise in good health, showed swelling and pain of the left inguinal-scrotal region. A testicular torsion was suspected, so the baby underwent an ultrasound examination of the testis and spermatic cord that showed a left scrotal hematoma with superior displacement of the didymus; the right testicle was located in the internal inguinal canal. Surgical intervention confirmed the sonographic diagnosis of left testicular hematoma and of the right cryptorchidism. CONCLUSIONS: Although testicular torsion is the most frequent cause of acute scrotum, the possibility of a persistent idiopathic scrotal haematoma and/or haematoma secondary to a trauma of the inguino-scrotal region, must be always taken into account. US diagnosis can avoid unnecessary emergency surgical treatment, required in case of testicular torsion.

Diffusion volume (DV) measurement in endometrial and cervical cancer: A new MRI parameter in the evaluation of the tumor grading and the risk classification.

PURPOSE: A new MRI parameter representative of active tumor burden is proposed: diffusion volume (DV), defined as the sum of all the voxels within a tumor with apparent diffusion coefficient (ADC) values within a specific range. The aims of the study were: (a) to calculate DV on ADC maps in patients with cervical/endometrial cancer; (b) to correlate DV with histological grade (G) and risk classification; (c) to evaluate intra/inter-observer agreement of DV calculation. MATERIALS AND METHODS: Fifty-three patients with endometrial (n=28) and cervical (n=25) cancers underwent pelvic MRI with DWI sequences. Both endometrial and cervical tumors were classified on the basis of G (G1/G2/G3) and FIGO staging (low/medium/high-risk). A semi-automated segmentation procedure was used to calculate the DV. A freehand closed ROI outlined the whole visible tumor on the most representative slice of ADC maps defined as the slice with the maximum diameter of the solid neoplastic component. Successively, two thresholds were generated on the basis of the mean and standard deviation (SD) of the ADC values: lower threshold (LT="mean minus three SD") and higher threshold (HT="mean plus one SD"). The closed ROI was expanded in 3D, including all the contiguous voxels with ADC values in the range LT-HT × 10-3mm(2)/s. A Kruskal-Wallis test was used to assess the differences in DV among G and risk groups. Intra-/inter-observer variability for DV measurement was analyzed according to the method of Bland and Altman and the intraclass-correlation-coefficient (ICC). RESULTS: DV values were significantly different among G and risk groups in both endometrial (p<0.05) and cervical cancers (p ≤ 0.01). For endometrial cancer, DV of G1 (mean ± sd: 2.81 ± 3.21 cc) neoplasms were significantly lower than G2 (9.44 ± 9.58 cc) and G3 (11.96 ± 8.0 cc) ones; moreover, DV of low risk cancers (5.23 ± 8.0 cc) were significantly lower than medium (7.28 ± 4.3 cc) and high risk (14.7 ± 9.9 cc) ones. For cervical cancer, DV of G1 (0.31 ± 0.13 cc) neoplasms was significantly lower than G3 (40.68 ± 45.65 cc) ones; moreover, DV of low risk neoplasms (6.98 ± 8.08 cc) was significantly lower than medium (21.7 ± 17.13 cc) and high risk (62.9 ± 51.12 cc) ones and DV of medium risk neoplasms was significantly lower than high risk ones. The intra-/inter-observer variability for DV measurement showed an excellent correlation for both cancers (ICC ≥ 0.86). CONCLUSIONS: DV is an accurate index for the assessment of G and risk classification of cervical/endometrial cancers with low intra-/inter-observer variability.

Prevention of cutaneous damages induced by radiotherapy in breast cancer: an institutional experience.

BACKGROUND AND AIMS: A minimal part of patients treated with radiotherapy on the entire breast may present an acute, subacute or chronic cutaneous damage of the healthy tissues involved in the radiation fields. The aim of this retrospective study was to evaluate the most efficient topical hydrating treatment in the prevention of cutaneous radio-induced acute effects in breast cancer. MATERIAL AND METHODS: From February 2009 to March 2010, 100 patients affected by breast cancer have been recruited, all of the female sex and with an average age of 47 years. The following topical treatments were compared: Pure vitamin E (Vea lipogel®), Omega-3,6,9 (Quinovit®), Betaglucan, sodium hyaluronate (Neoviderm®), Vitis vinifera A.s-I-M.t-O.dij, (Ixoderm®), natural triglycerides-fitosterols (Xderit®). All enrolled patients were subjected to breast conservative treatment (quadrantectomy with or without homolateral axillary dissection) and without prosthesis positioning, in combination or not with hormonal treatment. Evaluation of the cutaneous acute toxicity was defined according to the RTOG scale either during radiotherapy and during follow-up (3 months after radiation treatment). RESULTS: All patients completed the radiotherapy; 62% of patients presented G0-G1 cutaneous toxicity, 28% have developed G2 cutaneous toxicity, 10% have developed G3 toxicity; no patient presented G4 toxicity. Analysis of the data revealed a correlation between the topical treatment used and the incidence of cutaneous toxicity. CONCLUSIONS: Of the patients who used the cutaneous hydrating creams--betaglucan, sodium hyaluronate (Neoviderm®) and Vitis vinifera A.s-I-M.t-O.dij (Ixoderm®)--during the radiation treatment, 80% developed G0-G1 toxicity and 20% G2 toxicity. The patients who used the other hydrating creams tested in the study manifested not only G1-G2 toxicity but also some G3 toxicity. Chemotherapeutic treatment with taxanes and/or anthracyclines did not result in an increased breast cutaneous toxicity induced by radiotherapy. The hormone therapy given to patients undergoing radiotherapy did not result in increased breast cutaneous toxicity. Further analysis on a larger number of patients is necessary for definitive results.
