Fluorouracil, leucovorin and irinotecan combined with intra-arterial hepatic infusion of drug-eluting beads preloaded with irinotecan in unresectable colorectal liver metastases: side effects and results of a concomitant treatment schedule. Clinical investigation.

AIM: Safety evaluation of concomitant systemic chemotherapy and liver chemoembolization in patients with colorectal cancer. PATIENTS AND METHODS: Seven patients with metastases confined to the liver were included and stratified into two groups, depending of dosage of systemic chemotherapy. The first group received systemic chemotherapy (FOLFIRI) with 20% dose reduction, and the second group received the full dose of the same chemotherapy. In both groups, chemoembolization of liver metastases with drug-eluting bead irinotecan (DEBIRI) was performed following the application of systemic chemotherapy. The toxicity profiles of the two groups were compared. RESULTS: Of the 7 patients included, 4 received the reduced systemic chemotherapy dose and 3 received the full chemotherapy dose. DEBIRI was performed in all 7 patients. The main toxicities observed in the reduced chemotherapy dose group were leukopenia (25%), anorexia (75%), diarrhea (25%), vomiting (25%), right upper abdominal quadrant pain (100%) and elevated serum amylase level (25%). Main toxicities observed in the full chemotherapy dose group were anorexia (66.6%), vomiting (33.3%), right upper abdominal quadrant pain (100%), and elevated serum amylase level (66.6%). There were no significant differences between the two groups ( P = 0.78541). CONCLUSIONS: Patients with isolated liver metastases from a colorectal primary can safely be treated with DEBIRI chemoembolization and a full dose of systemic chemotherapy (FOLFIRI).

Successful resection of hepatocellular cancer not amenable to Milan criteria and durable complete remission induced by systemic polichemotherapy after development of metastases - should we think about revising the current treatment guidelines in selected patients?

OBJECTIVES: To refresh clinical diagnostic and therapeutic dilemmas in patients presenting with hepatocellular cancer (HCC) and to report a rare success of systemic polichemotherapy in metastatic HCC. METHODS: Case report of a patient with successfully resected HCC although initially deemed inoperable according to current guidelines, and who was successfully treated by systemic polichemotherapy after development of metastatic disease, resulting in a sustained complete remission. RESULTS: We describe a 71-year-old female with HCC initially treated by atypical liver resection, although not amenable to initial surgery according to current treatment guidelines, which resulted in 6 months disease-free interval. After development of pulmonary metastases, the patient was treated by systemic polichemotherapy, due to local unavailability of novel biologic agents. After 3 months of chemotherapy biochemical remission was confirmed, and after 10 months of active treatment complete radiological remission was verified according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria, now exceeding 9 months in duration. CONCLUSION: There is an increasing body of evidence that criteria for surgical interventions in HCC should be revised and expanded, and our case is an example of such an approach. Although novel biologic therapies are not widely available in all regions of the world due to their cost, currently there are no hard recommendations for use of chemotherapy in such areas. Since this is a large problem in clinical practice, we conclude that chemotherapy should be offered to selected patients of good performance status if novel agents are unavailable.

Paraneoplastic stiff person syndrome associated with colon cancer misdiagnosed as idiopathic Parkinson's disease worsened after capecitabine therapy.

OBJECTIVES: To refresh clinical diagnostic dilemmas in patients presenting with symptoms resembling to those of parkinsonism, to report rare association of colon cancer and paraneoplastic stiff person syndrome (SPS), and to draw attention on the possible correlation of capecitabine therapy with worsening of paraneoplastic SPS. METHODS: Case report of the patient with paraneoplastic SPS due to colon cancer that was misdiagnosed as idiopathic Parkinson's disease (iPD), whose symptoms worsened after beginning adjuvant capecitabine chemotherapy. RESULTS: We describe a 55-year-old woman with subacute onset of symmetrical stiffness and rigidity of the truncal and proximal lower limb muscles that caused lower body bradykinesia, gait difficulties, and postural instability. Diagnose of iPD was made and levodopa treatment was initiated but failed to provide beneficial effect. Six months later, colon cancer was discovered and the patient underwent surgical procedure and chemotherapy with capecitabine thereafter. Aggravation of stiffness, rigidity, and low back pain was observed after the first chemotherapy cycle and capecitabine was discontinued. Furthermore, levodopa was slowly discontinued and low dose of diazepam was administered which resulted in partial resolution of the patient's symptoms. CONCLUSION: Paraneoplastic SPS is rare disorder with clinical features resembling those of parkinsonian syndrome and making the correct diagnosis remains a challenge. The diagnosis of parkinsonian syndrome should be re-examined if subsequent examinations discover an associated malignant process. Although it remains unclear whether the patients with history of SPS are at the greater risk for symptoms deterioration after administration of capecitabine, clinicians should be aware of capecitabine side effects because recognition and appropriate management can prevent serious adverse outcomes.

Sex or surgery--erectile dysfunction after radical treatment of localized prostate cancer.

The maintenance of satisfactory quality of life is major concern in majority of patients who elect treatment for localized prostate cancer. We conducted a cross-sectional study to determine sexual function after radical prostatectomy (RP) and external beam radiotherapy (EBRT). Study population consisted of series of 57 patients with early-stage adenocarcinoma of the prostate, treated in our institution in the period from January 2003 till December 2003. Thirty three patients underwent radical retropubical prostatectomy and 24 patients were treated by primary radical radiotherapy. Patients have been given the full international index of erectile function (IIEF) questionnaire two to four and six months after the treatment. Post treatment sexual function in patients treated by EBRT is significantly better than in patients treated by RP (48.5% vs. 21.57%, p < 0.0001). Subgroup analysis reveals that satisfaction with erectile function, maintaining of sexual intercourse and possibility of ejaculation is better in patients treated by EBRT than in patients treated by RP (44.67% vs. 11.57%, p < 0.0001) as well as general satisfaction with quality of sexual life (48.5% in EBRT group vs. 21.57% in RP group, p < 0.0001). On the other hand, sexual desire remains the same in both groups of patients (63.75% in EBRT group vs. 60.61% in RP group, p = 0.71). Six months after surgical or radiotherapy treatment erectile function is almost as twice as worse in patients treated by surgery than in patients treated by radiotherapy.

[Side effects of radiotherapy in oral cavity: diagnosis, prevention and treatment guidelines]. / Nuspojave radioterapije u usnoj supljini: dijagnostika, prevencija i terapijske smjernice.

To avoid, or at least to reduce complications in patients who require head and neck radiotherapy, adequate oral cavity treatment is necessary before the therapy. Recent management guidelines speak of possibilities of preventing osteoradionecrosis with hyperbaric oxygen, using long-wave ultrasound in stimulating osteoblasts growth, and surgical transfer of submandibular salivary glands to submental area with 99% effectiveness in preventing xerostomia, besides traditional therapy. Preventive measures are naturally the best choice, since late complications treatment is not needed as often, and should draw special attention of physicians and patients. Since wide a spectrum of preventive and curative measures is required, the need exists for standard teams to look after the patients during and after radiotherapy, and which should include, besides radiotherapist, oral or maxillofacial surgeon in cooperation with oral medicine specialist.

Treatment of cancer-related anemia.

Anemia with consequent tissue hypoxia is common problem in cancer patients. Developed via various patophysiological mechanisms, it has deleterious effect on quality of life and survival of patients with cancer. Recognition of symptoms and timely initiation of treatment improve patients' quality of life, as well as efficacy of oncological treatment. Red blood cells transfusions are well known and efficient way of anemia correction. They are "golden standard" in treatment of cancer-related anemia today, and are unavoidable in almost all patients with hemoglobin concentration below 80 g/L. Newest therapy guidelines in developed countries, supported by recent literature, encourage use of recombinant human erythropoietin (rHu-EPO), although detailed meta-analyses and prospective randomized clinical trials have shown that rHu-EPO decreases the need for transfusions in only 9-45% patients with cancer, only if they have mild anemia, rHu-EPO increases incidence of thromboembolic events, and suspicion arises that it supports tumor cells growth and multiplication. Therefore, it is necessary to define subgroups of patients which are best candidates for rHu-EPO therapy, to accomplish lower intensity of transfusion therapy.

Erdheim-Chester disease and concomitant tuberculosis successfully treated with chemotherapy and long-term steroids.

Erdheim-Chester disease (ECD) is a rare histiocytosis usually affecting the skeletal system, but visceral organs and central nervous system involvement are common as well. Probability exists that immunomodulatory therapies and disorders can play a role in clinical course of the disease. Because of rarity of the disorder, it is hard to classify it and standardize the treatment options, but, according to published material and our experience, cytotoxic chemotherapy and long-term steroids have therapeutic benefit. Although this approach can probably be accepted as standard of care management, novel therapeutic modalities should be explored, and pathogenesis and disorder classification should be cleared out as well. The case of ECD affecting skeletal system and lungs and concomitant laryngeal tuberculosis successfully treated with chemotherapy and long-term steroid therapy is presented.
