neuroendocrine cancer therapeutic strategies in g3 cancers

Green Gate, Bd. Tudor Vladimirescu nr. We present a case of a solitary pulmonary nodule discovered in a patient with resected rectal carcinoma, irradiated and chemotreated controlled disease. The initial management was CT follow-up; because the nodule dimensions increased, the surgical resection was performed: wedge pulmonary resection and lymphadenectomy.

The pathological diagnosis was stage IA lung adenocarcinoma. A newly appeared solitary pulmonary nodule in a patient with a history of malignancy could be a metastasis, however could also be a second primary cancer - lung cancer.

Wedge pulmonary resection human neuroendocrine cancer therapeutic strategies in g3 cancers infection untreated lymphadenectomy is an appropriate surgical management for stage IA lung cancer in selected patients; this approach impose close follow-up for early detection of a local relapse. Diagnosticul anatomopatologic a fost de adenocarcinom pulmonar stadiul IA. Solitary pulmonary nodules are usually asymptomatic and most frequently conceal lung cancer 2.

Cancer risk increases with age, male gender and a smoking history. The nonneoplastic benign nodules are most commonly due to granulomas from prior infections and in our country, neuroendocrine cancer therapeutic strategies in g3 cancers a significant number of patients, they are caused by Mycobacterium tuberculosis 4. Solitary pulmonary nodules in patients with a history of malignancy other than lung cancer have a higher chance of being metastatic.

Still, due diligence of a solitary pulmonary nodule is to treat it as an indeterminate nodule, with the possibility of being lung cancer, metastasis or a benign lesion 2,5. CT scan follow-up of the pulmonary nodule at 6 months revealed growth from 1. Figure 1. Native CT scan image of a left solitary pulmonary nodule presented case Figure 2. Contrast-enhanced CT scan image of the same solitary pulmonary nodule as in figure 1; the well-deligneated contour and the geographic area of endemic tuberculosis are benign criteria Results Following completion of clinical and paraclinical investigations and maintenance of her arterial hypertension we proceeded to surgery, performing a nonanatomic resection of the left superior lobe.

The intraoperative frozen section histopathology showed carcinomatous infiltration without being able to neuroendocrine cancer therapeutic strategies in g3 cancers a histological origin. The final paraffin embedded histological sections and immunohistochemical tests confirmed lung cancer: a poorly differentiated G3 adenocarcinoma, without lymph node metastasis, pathological stage IA, pT1bN0M0.

The postoperative recovery was uneventfull, facilitated following a nonanatomical resection.

The patient was forwarded towards the oncology ward. The therapeutical decision was follow-up. Discussion Figure 3. Spiculated aspect of the nodule; this aspect and the upper lobe localization, the history of malignancy, age over 35 years, dimension over 2 cm and growth in time summarize the malignant characteristics of the solitary pulmonary nodule 6 The prevalence of solitary pulmonary nodules in the general population is unknown.

Higher rates are found in the elderly population, among smokers, in patients with nonthoracic neoplasms and in patients who are at risk for mycobacterial or fungal infections 2,6.

In Romania, there is no protocol for screening solitary pulmonary nodules or lung cancer. Owing to its superior resolution, high-resolution CT is a sensitive technique for identifying pulmonary nodules 4. The American Vaccinazione papilloma virus adulti of Chest Physicians developed an evidence-based clinical guideline neuroendocrine cancer therapeutic strategies in g3 cancers help establish the probability of malignancy of a pulmonary nodule 1.

Predictors of malignancy include: older age, current or past smoking, history of extrathoracic cancer in the last 5 years, nodule diameter, spiculation and upper lobe location 2,5. PET-CT is a noninvasive functional imaging modality used for diagnosis, staging and evaluation of treatment response of lung cancer. PET-CT is not indicated for nodules that are under 0.

For lesions that are located in the center of the lung, we can use bronchoscopy with fluoroscopic guidance 9.

For nodules situated in the neuroendocrine cancer therapeutic strategies in g3 cancers third of the lung, transthoracic needle biopsy can help obtain a diagnosis. With a higher number of biopsy samples taken and a good on-site cytopathologyst, one may obtain a higher rate of positive results However, the imaging characteristics figures 1, 2, 3 classified it as an indeterminate nodule, and therefore compelled us to also consider lung cancer as a possibility.

Considering she had multiple predictors of malignancy: growth over time, extra thoracic cancer neuroendocrine cancer therapeutic strategies in g3 cancers the last 5 years, the nodule was in an upper lobe of the left lungwe decided that the best conduct is surgery. Conclusions A newly appeared solitary pulmonary nodule in a patient with a history of malignancy could be a metastasis, however could also be a second primary cancer - lung cancer.

Updated: Apr 30,accessed at Nov 17, Until trastuzumab erathe HER-2 overexpression was a negative prognostic factor and lead to a poor treatment outcome. Modern treatment is represented by combination of chemotherapy and therapies addressed to HER-2 - among classic trastuzumab, lapatinib, TDM -1 trastuzumab etamsine and pertuzumab, new options arise - neoadjuvant pertuzumab, and a new potential treatment with a another TKI tyrosine kinase inhibitor - Neratinib.

In our country there is only trastuzumab available after submission of documents and approval from National Health Insurance Housewith 2 routes of administration IV-intravenous and SC- subcutanein adjuvant, metastatic and recently in neoadjuvant setting.

For Romania, breast cancer is still a major problem, taking in account the lack of a consistent national health screening program, late stage diagnosis and high mortality rates. Data regarding safety neuroendocrine cancer therapeutic strategies in g3 cancers are also shown especially concerning cardiac toxicity.

Considering that efficient screening programs and multidisciplinary teams are available, by using neoadjuvant treatment, best survival and esthetic results are obtained; this option will be more detailed.

A mention will be made for the surgical interventions needed. Some treatment options are only available in certain countries. As always recommended by guidelines, patient case must be discussed in multidisciplinary team and, if possible, after evaluation, and if needed and available, patient should be encouraged to participate in a clinical trial.

A possible evaluation of the patient before any cancer du colon hpv of treatment in a multidisciplinary team brings more benefit for the patient. Of course, neoadjuvant treatment is in many cases necessary and a close collaboration with the surgeon, radiotherapist, anatomopathologist, interventional radiologist if taking in account image guided clip insertion harvests best results.

The Phare study did not manage to demonstrate the non-inferiority of Trastuzumab administration for 6 month instead of neuroendocrine cancer therapeutic strategies in g3 cancers month 8. None of the guidelines recommend in neoadjuvant setting the association of trastuzumab and lapatinib 1,2. The studies which showed the benefits of double HER-2 therapy in neoadjuvant treatment are NeoSpere almost double complete pathologic response - pCR vs.

Although severe cardiac events like congestive heart failure are rare and usually reversible after stopping the treatment, there are studies which try to asses new markers that reflect earlier the dysfunction neuroendocrine cancer therapeutic strategies in g3 cancers left ventricle. Association of concomitant trastuzumab and taxane is safe and beneficial when compared to subsequent treatment As expected, after neoadjuvant chemotherapy it is very possible that the tumor would be difficult to be found by the surgeon at the moment of excision.

Usual option in this case would be placing, wart on foot removal guided imaging, of clips before chemotherapy treatment, which will facilitate correct conservative neuroendocrine cancer therapeutic strategies in g3 cancers of tumor afterwards.

Also at the moment of surgery, after the removal of the tumor, another set of guidance clips may be placed, which will facilitate the radiotherapy doctor in planning an efficient localized treatment.

Metastatic setting Pertuzumab is approved in combination with trastuzumab and chemotherapy as a first-line therapy for metastatic HERpositive breast cancer patients In patients who have progression after initial therapy, anti-HER-2 therapy should be continued by either switching neuroendocrine cancer therapeutic strategies in g3 cancers TDM-1 preffered 9 breast cancer or neuroendocrine cancer therapeutic strategies in g3 cancers trastuzumab and changing cytotoxic therapy or switching to lapatinib plus capecitabine 2.

Patients who received T-DM1 treatment lived almost 6 months longer compared with patients receiving lapatinib plus capecitabine, the previous standard of care median overall survival There are ongoing studies investigating TDM-1 in adjuvant setting.

There was a significant improvement in disease-free survival DFS with an absolute benefit of 2. Of great interest, patients with HR-positive breast cancer had even greater benefit from neratinib 4. There was no protocol-mandated antidiarrheal prophylaxis in place. Like lapatinib, neratinib is orally available, and pharmacokinetic studies have suggested that once-daily dosing is acceptable.

Neratinib after adjuvant chemotherapy and trastuzumab in HERpositive early breast cancer: Primary analysis at 2 years of a phase 3, randomized, placebo-controlled trial ExteNET. Abstract For a very long period of time, the only treatment option neuroendocrine cancer therapeutic strategies in g3 cancers for fit patients was chemotherapy with Docetaxel associated with Prednisone. The recent approval in our country neuroendocrine cancer therapeutic strategies in g3 cancers new therapies like Abiraterone, will offer new treatment options which will enhance disease control and safety profile for selected patients.

We have reviewed over 50 articles published neuroendocrine cancer therapeutic strategies in g3 cancers international journals, to offer an extensive view of therapeutic agents used in the management of CRPC, from chemotherapy agents, hormonal treatment, to new androgen receptor inhibitors, immunotherapy and prevention and palliative treatment of bone metastasis and SRE skeletal related events with bisphosphonates, radiotherapy and radiopharmaceuticals.

The average age at diagnosis is 71 years. Screening healthy men by means of prostate specific antigen PSA increases PC incidence and determines overdiagnosis.

Subclinical forms of prostate cancer are common in men over 50 years old.

According to recent studies, the effect of intense screening and early treatment on mortality rates remains controversial. The best-known risk factors for PC are: age, family history risk increases two times if a first degree relative suffers from PCrace in the US, neuroendocrine cancer therapeutic strategies in g3 cancers incidence is higher in black people than in Caucasiansgeographical location low incidence in Asia, high incidence in Scandinavia and US and nutrition increased animal fat intake is a possible risk factor, but its role has not been fully established in the ethiology of PC.

The prostate biopsy should be guided by trans rectal echography and at least eight tissue samples should be collected. A well-performed prostate biopsy allows the pathologist to assess the Gleason score, which is essential for determining prognosis and management. InHuggins and Hudges discovered that prostate tumours are almost entirely hormone-dependent. Initially, hormone therapy HT was used in advanced stages of PC, when the patient had symptoms or metastases diagnosed by imaging studies.

Currently, androgen deprivation therapy ADT is the treatment of choice for all stages of PC; ADT is also used as a neoadjuvant or adjuvant treatment before or after radiotherapy. No hormonal therapy is superior to another! Patients are monitored by means of serum PSA and regular imagistic studies. However, a subpopulation of prostate tumour cells acquires resistance to anti-androgen therapies and becomes dominant, resulting in hormone resistance resistance to castration.

The increase of PSA serum values, in spite of low plasma testosterone, represents the transition towards the hormone-resistant stage, which is considered lethal for most patients. In some cases, new metastases can be diagnosed without increased PSA values. The disease can be symptomatic or asymptomatic. Extra-osseous metastatic disease can develop also in rare sites, such as adrenal gland, kidney, pancreas and brain.

Pathophysiology In CP, androgens are produced by: n Leydig testicular cells; n cholesterol conversion through the cytochrome system; n prostate tumour tissue autocrine secretion of androgens. The conversion of prostate cancer towards CRPC requires the development of adaptive pathways for transmitting the intracellular signal in an androgenfree environment. This also includes the activation of other receptors, like the ones for the epidermal growth factor or the tyrosine-kinases receptors; n alternative intracellular signalling pathways also represent a mechanism involved in the transition to CRPC.

This activation can inhibit the apoptosis induced by anti-androgen therapy through Bc anti-apoptotic protein activation; n studies have shown that a subpopulation of PC tumour cells is made of undifferentiated stem cells which do not express androgen receptors, and thus they do not depend on androgens for survival.

This regimen can delay disease progression or prevent the occurrence of metastases, though there is no definitive clinical evidence to support this outcome. Nevertheless, usually, this response is short-lasting, months, and it appears weeks after therapy discontinuation.

Chirurgia Bucur ; 4 : Due to the fact that the consequences in terms of postoperative morbidity can delay the onset of postoperative chemotherapy or even can make the patient unfitted for adjuvant treatment, a thorough clinical evaluation of patient prior to surgery is mandatory.

Metastatic CRPC Maintaining testosterone at castrate levels, even after PC transitions to CRPC, is considered gold standard both in the locally-advanced and the metastatic disease, because androgen receptor and the intracellular androgen levels remain significantly elevated even in hormone resistant PC patients.

Constant androgenic suppression increases survival for patients with CRPC. Studies report that medication withdrawal was successful for the following agents: flutamide, bicalutamide, nilutamide, megestrol acetate, diethylstilbestrol, estramustine. The response to discontinuing the anti-androgen medication appears after weeks, depending on the half-life of the drug.

For example, flutamide, with a half-life of weeks, will determine a faster response than bicalutamide, which neuroendocrine cancer therapeutic strategies in g3 cancers a longer half-life. Most studies report that steroid therapy has demonstrated a decrease in PSA levels, which is associated with increased survival.
