The role of rehabilitative camouflage after cervicofacial reconstructive surgery: a preliminary study.

A randomized, prospective, controlled study was carried out at the Plastic and Reconstructive Surgery Unit of the University of Pavia, Salvatore Maugeri Research and Care Institute, Pavia, Italy, to evaluate the psychological benefits from corrective medical camouflage (CMC) following surgical treatment for skin cancer of the face. Twenty-four female patients, following recovery from facial skin cancer surgery, were enrolled in the study over a period of 1 year. The study was performed using two health-related quality of life tests, the Satisfaction Profile (SAT-P) test and the Body Uneasiness Test (BUT). The patients were randomized into two groups: group A, patients undergoing CMC; and group B, controls. Both the SAT-P and BUT demonstrated statistically significant better results in the treated patients versus the controls in the following functional parameters: Psychological Functionality (PsF), Physical Functionality (PhF), and Work Performance (WP) for the SAT-P test and Compulsive Self-Monitoring (CSM) for the BUT. The PsF demonstrated a better result 6 months post-treatment. Such a difference was particularly significant when comparing the performance at 6 months versus that at 3 months. The PhF demonstrated a better outcome at 6 months post-treatment. The WP demonstrated a better result comparing the performance at 6 months versus that at 3 months. The CSM demonstrated a better outcome at 6 months post-treatment. The CMC promoted a significant improvement in patients' physical appearance and in their self-image and perceived social role as a means of their desire to disguise their body disfiguration.

Prevalence, incidence and types of mild anemia in the elderly: the "Health and Anemia" population-based study.

BACKGROUND: Hemoglobin concentrations slightly below the lower limit of normal are a common laboratory finding in the elderly, but scant evidence is available on the actual occurrence of mild anemia despite its potential effect on health. The objectives of this study were to estimate the prevalence and incidence of mild grade anemia and to assess the frequency of anemia types in the elderly. DESIGN AND METHODS: This was a prospective, population-based study in all residents 65 years or older in Biella, Italy. RESULTS: Blood test results were available for analysis from 8,744 elderly. Hemoglobin concentration decreased and mild anemia increased steadily with increasing age. Mild anemia (defined as a hemoglobin concentration of 10.0-11.9 g/dL in women and 10.0-12.9 g/dL in men) affected 11.8% of the elderly included in the analysis, while the estimated prevalence in the entire population was 11.1%. Before hemoglobin determination, most mildly anemic individuals perceived themselves as non-anemic. Chronic disease anemia, thalassemia trait, and renal insufficiency were the most frequent types of mild anemia. The underlying cause of mild anemia remained unexplained in 26.4% of the cases, almost one third of which might be accounted for by myelodysplastic syndromes. In a random sample of non-anemic elderly at baseline (n=529), after about 2 years, the annual incidence rate of mild anemia was 22.5 per 1000 person-years and increased with increasing age. CONCLUSIONS: The prevalence and incidence of mild anemia increase with age and mild anemia affects more than one out of ten elderly individuals. Unexplained anemia is common and may be due to myelodysplastic syndromes in some cases.

Erlotinib administration for advanced non-small cell lung cancer during the first 2 months of unrecognized pregnancy.

Although several antineoplastic agents have been proven to be safe for the fetus after the organogenesis period, there is limited information on their use during the first trimester of pregnancy. Herein we report the first case of a patient with metastatic lung cancer treated with erlotinib during the first 2 months of an unrecognized pregnancy. A 30-year-old woman was diagnosed with stage IV non-small cell lung cancer with bone and lung metastasis. The patient received 4 months of palliative cisplatin/gemcitabine chemotherapy and biphosphonates. After 12 months the disease progressed and the patient received erlotinib 100 mg/day. During this period the patient became pregnant. Since she recalled the date of her last menstrual period at about 15 days prior to the start of the therapy, we did consider the possibility of conception at the time of the first day of erlotinib administration. Informed about the risk for the fetus due to erlotinib, the patient stopped anticancer treatment. After 42 weeks of regular gestation, cesarean section was performed, delivering a 3490 g female new-born with no evidence of congenital malformations. The disease evaluation performed with thoracic CT scan, after 1 month from the childbirth, showed a progressive lung metastasis and erlotinib treatment was resumed at the dose of 150 mg/day.

Bisphosphonate-associated osteonecrosis of the jaw: a review of 35 cases and an evaluation of its frequency in multiple myeloma patients.

Over a period of 28 months, we observed five cases of osteonecrosis of the jaw (ONJ) in cancer patients treated with bisphosphonates (BP) at our institution. This prompted us to undertake a retrospective, multicenter study to analyse the characteristics of patients who exhibited ONJ and to define the frequency of ONJ in multiple myeloma (MM). We identified 35 cases in Gruppo Italiano Studio Linfomi centers during the period 2002 - 05. The median time from cancer diagnosis to the clinical onset of ONJ was 70 months. In these 35 cases of ONJ, 24 appeared 20 - 60 months after starting BP treatment. The time for the onset of ONJ was significantly shorter for patients treated with zoledronic acid alone than for those treated with pamidronate followed by zoledronic acid. The frequency of ONJ in the MM group during the study period was 1.9%, although the nature of the present study may have resulted in an underestimation of ONJ cases. Our analysis strongly suggested an association between the use of BP and the occurrence of ONJ, although we were unable to identify any definite risk factors with a retrospective study. The most frequently ONJ-associated clinical characteristics were chemotherapy treatment, steroid treatment, advanced age, female sex, anemia, parodonthopaties/dental procedures and thalidomide (in the case of MM patients).

Peripheral blood progenitor cell collection in chronic myeloid leukemia patients with complete cytogenetic response after treatment with imatinib mesylate.

BACKGROUND: Imatinib mesylate (IM) was introduced in chronic myeloid leukemia (CML) treatment in the late 1990s and substantially changed the therapeutic approach to the disease, by inducing complete cytogenetic response (CCR) in approximately 60 percent of cases. Nevertheless, some concerns exist about the duration of response to treatment and the onset of resistance to IM. STUDY DESIGN AND METHODS: Twenty-five chronic-phase CML patients in stable CCR (>6 months) treated for at least 1 year with IM at the standard dose (400 mg/day) were mobilized with recombinant human granulocyte-colony-stimulating factor (Filgrastim) at 10 microg per kg for 4 to 6 days, with the aim of collecting at least 2 x 10(6) CD34+ cells per kg. Standard cytogenetic analysis and first-round and/or nested polymerase chain reaction were performed in basal and postmobilization samples to examine the presence of bcr-abl transcripts. RESULTS: CD34+ cells collection was successful in 16 patients, yielding a median of 3.01 x 10(6) +/- 1.09 x 10(6) CD34+ cells per kg at the first attempt, and in 4 of the 9 remaining patients who were remobilized after a temporary withdrawal of IM, yielding a median of 2.65 x 10(6) +/- 0.7 x 10(6) CD34+ cells per kg, with an overall 80 percent success rate. No correlation between mobilization and duration of the disease, length of IM treatment, or previous interferon-alpha and/or hydroxyurea treatment was found. CONCLUSIONS: Autologous CD34+ cells may be mobilized and collected in most CML patients who achieve CCR after IM treatment, with a view to possible use in the event that resistance to IM occurs in patients not eligible for allogeneic peripheral blood progenitor cell transplantation or those lacking an HLA-matched donor.

Pilot study of the mechanism of action of preoperative trastuzumab in patients with primary operable breast tumors overexpressing HER2.

PURPOSE: To elucidate the mechanism by which trastuzumab, a humanized monoclonal antibody against HER2 with proven survival benefit in women with HER2-positive metastatic breast cancer, mediates its antitumor activity. EXPERIMENTAL DESIGN: A pilot study including 11 patients with HER2-positive tumors treated in a neo-adjuvant setting with trastuzumab was performed. Trastuzumab was administered i.v. at a dose of 4 mg/kg followed by three weekly i.v. doses of 2 mg/kg. The primary tumor was surgically removed 7 days after the last treatment. Surgical samples, tumor biopsies, and lymphocytes from these patients were collected for biological studies. RESULT: Clinical data indicated one complete pathological remission and four partial remissions using RECIST (Response Evaluation Criteria in Solid Tumors). Trastuzumab was well tolerated and neither serious adverse events nor changes in cardiac function were observed during this short-term treatment and after surgery. The biological data showed that, independent of response, (a) all patients showed high levels of circulating trastuzumab; (b) saturating level of trastuzumab was present in all of the tumors; (c) no down-modulation of HER2 was observed in any tumors; (d) no changes in vessel diameter was observed in any tumors; (e) no changes in proliferation was observed in any tumors; and (f) a strong infiltration by lymphoid cells was observed in all cases. Patients with complete remission or partial remission were found to have a higher in situ infiltration of leukocytes and a higher capability to mediate in vitro antibody-dependent cellular cytotoxicity activity. CONCLUSIONS: The results of this pilot study argue against trastuzumab activity in patients through down-modulation of HER2 but in favor of antibody-dependent cellular cytotoxicity guiding efforts to optimize the use of trastuzumab in breast cancer patients.

Retrorectal tumours: a case report.

The authors describe a case of retrorectal tumour in a 48-year-old female. Retrorectal tumours are rare, and their diagnosis is notoriously difficult and late. In this case the first-step diagnosis was made on the basis of clinical findings and radiological investigations such as abdominal ultrasonography. The second step included pelvic CT scans and MR imaging which yielded more precise anatomical details and information for the best surgical approach. We opted for a posterior approach with complete, easy removal of the tumour mass which, after pathological examination, turned out to be an epidermoid cyst. The postoperative course was uneventful and, one year after operation, the patient complains only of mild, irregular perineal pain with completely negative radiological investigations (US and CT scan).

T-cell dynamics after high-dose chemotherapy in adults: elucidation of the elusive CD8+ subset reveals multiple homeostatic T-cell compartments with distinct implications for immune competence.

Recovery of total T cell numbers after in vivo T-cell depletion in humans is accompanied by complex perturbation within the CD8+ subset. We aimed to elucidate the reconstitution of CD8+ T cells by separate analysis of putative naïve CD95- CD28+, memory CD95+ CD28+ and CD28- T cell compartments after acute maximal depletion by high-dose chemotherapy (HD-ChT) in women with high-risk breast cancer. We found that recovery of putative naïve CD8+ CD95- CD28+ and CD4+ CD95- CD28+ T cells, was compatible with a thymus-dependent regenerative pathway since their recovery was slow and time-dependent, their values were tightly related to each other, and their reconstitution patterns were inversely related to age. By analysing non-naïve T cells, a striking diversion between putative memory T cells and CD28- T cells was found. These latter increased early well beyond normal values, thus playing a pivotal role in total T-cell homeostasis, and contributed to reduce the CD4 : CD8 ratio. In contrast, putative memory T cells returned to values not significantly different from those seen in patients at diagnosis, indicating that this compartment may recover after HD-ChT. At 3-5 years after treatment, naïve T cells persisted at low levels, with expansion of CD28- T cells, suggesting that such alterations may extend further. These findings indicate that CD28- T cells were responsible for 'blind' T-cell homeostasis, but support the notion that memory and naïve T cells are regulated separately. Given their distinct dynamics, quantitative evaluation of T-cell pools in patients undergoing chemotherapy should take into account separate analysis of naïve, memory and CD28- T cells.

Evaluation of infectious complications and immune recovery following high-dose chemotherapy (HDC) and autologous peripheral blood progenitor cell transplantation (PBPC-T) in 148 breast cancer patients.

BACKGROUND AND OBJECTIVES: High-dose chemotherapy (HDC) with autologous PBPC-T has been reported to be effective in hematological and in selected solid malignancies. In this setting, infectious complications represent a relevant cause of morbidity. PATIENTS AND METHODS: To ascertain the incidence, types and factors influencing the development of early and late infections, we retrospectively analyzed 148 consecutive breast cancer (BC) patients receiving HDC and PBPC-T, both for primary high-risk BC (pBC) and metastatic disease (mBC). RESULTS: Early infection strongly associated with the occurrence of grade 4 mucositis (p < 0.001), was documented in 28 patients (19%). Late re-activation of varicella zoster virus (VZV) occurred in 14 patients (9%); an inverse correlation between the VZV re-activation and the total amount of T-cells transferred with the graft was observed. Evaluation of immune reconstitution, carried out in 10 out of 148 patients, showed a long-lasting CD+ T-cells depression (> 2 year), mainly involving the naive CD4+ T-cell subset. Conversely, the analysis of the frequency of proliferating T-lymphocyte precursors, specific for antigens expressed by 3 different widespread pathogens, demonstrated that, notwithstanding the delayed recovery of CD4+ cells, many T-lymphocyte functions were within normal range 1 year after PBPC-T. CONCLUSION: Altogether these results show that severe mucositis is associated with early bacterial infections and the infusion of large numbers of T-cells plays a role in controlling late VZV reactivation.
