A male patient, years-old, from urban area, presents at clinic in July History: April - he presents at the hospital for laterocervical lymph nodes, surgically removed.
Risk factors: non-smoker, without professional exposure, alcohol occasionally. Comorbidities: surgery for repair of mitral valve after endocarditis and surgery for femural head avascular necrosis Computer tomography CT of cervical area, thorax and abdomen, in Aprilfound left pulmonary lesion without specificity, thin, 8 mm fluid accumulation in left costodiafragmatic sinus.
Suspect bone lesion on right iliac wing and sacroiliac articulation.
Bilateral osteolytic lesions on hip head, accentuated on the right one suggestive for aseptic osteonecrosis - known from patient history. Bronhoscopy and cytology only offered indications about category of tumor SCLC or NSCLC - in our case without being able to orient us regarding exact histology adenocarcinoma, squamos, or large cell. With results from PET-CT and bronhoscopy, and needing to asses exact tumor type, most accessible lesions are removed June - left thyroid lobe, left parotid and histopathology and IHC examination requested.
They proved to be metastasis of lung adenocarcinoma. After suspicion of metastatic cancer lung treatment metastasis on PET CT, scintigraphy is recommended to bring more details regarding bone lesions, which shows right hip head hyperfixation aseptic necrosis in metastatic cancer lung treatment statesuspicious metastatic cancer lung treatment lesion on right sacroiliac articulation, which needs monitoring.
No intervention is taken regarding the bone, with close monitoring of current lesions. Genetic tests: EGFR mutations exons 18, 19, 20, 21 - metastatic cancer lung treatment present. Diagnostic Clinical suspicion of lung neoplasm, sustained by imagistic studies PET-CTand confirmed by histopathology and immunohistochemistry results. Final diagnostic: metastatic cancer lung treatment small cell lung cancer adenocarcinoma of left pulmonary lobe with pleural, bone, thyroid and salivary gland metastasis last two operatedstage IV.
Differential diagnostic: neoplasm of thyroid and neoplasm of salivary gland - which were differentiated by immunohistochemistry. Treatment Because of present symptomatology and patient preference to start treatment as soon as possible, we opted for chemotherapy - platinum doublet.
He has undergone conformational RT on target volume and lymph nodes area, total dose 60 Gy, well supported. After finalizing Papillomavirus ou mycose, patient is continued on Alimta maintenance, with good results, that confirm the data from studies that registered the concept of switch maintenance pemetrexed.
After 2 cycles - neutropenia grade 3, required administration of filgrastim and delay of cycle 3 with 2 days ; mucositis grade 2 - symptomatic treatment. After 4 cycles - sensory peripheral neuropathy grade 2; sent to neurologic consult - symptomatic treatment. After 18 cycles, in January - neurologic symptoms occur - numbness and muscular weakness in right hand motor neuropathy grade 3 - initially considered a potential clinical sign of brain metastasis.
Neurologic consult shows right radial nerve palsy; it was recommended MRI for cerebral and cervical region. EMG showed axonal sensitive neuropathy in all limbs, axonal mononeuropathy of radial nerve with important acute denervation suggestive for lesion of posterior interosseous nerve and recommends monitoring.
Motor neuropathy is considered of mixed etiology, and treatment with Alimta is continued. Close term prognostic, as long as response to treatment is maintained, is good. Medium term prognosis is relatively good. Long term prognosis is a reserved one.

The patient has never smoked and it has been demonstrated that these patients have better prognostic and respond better to chemotherapy. Some data suggest the opportunity to include these patients in a different subgroup 2. In this case, although EGFR mutation was not detected, and there were numerous initial metastasis sites, response metastatic cancer lung treatment treatment and survival are very good present time: 1 year and 8 months.
Evolution In JanuaryCT TAP - without tumoral lesions in mediastinum, pleural or lung; no enlarged lymph nodes, no lesions suspected for metastasis, right iliac wing - 7 mm lesion suggestive for osteoblastoma a rare primary neoplasm of bone, categorized as a benign bone tumor that is closely related to osteoid osteoma.
Patient will receive 21 metastatic cancer lung treatment cycles of maintenance chemotherapy until the disease progression or inacceptable toxicity. Regarding maintenance with pemetrexed Alimtathere are two important studies that demonstrate the role of this drug in continuous and switch maintenance.
In Paramount study, Pemetrexed continuation maintenance therapy was well tolerated and it was obtained a superior overall metastatic cancer lung treatment compared with placebo.
This study demonstrated that continuous maintenance is an effective treatment strategy for patients with advanced non squamous non small-cell lung cancer and good performance status that did not progress during pemetrexed-cisplatin induction therapy 3.
The benefit of switch maintenance was demonstrated by JMEN study. Both groups received vitamin B12 and folic acid, metastatic cancer lung treatment is standard for Alimta. The trial was clearly positive for demonstrating a benefit in progression-free survival as well as higher response rates achieved in patients overall who received Alimta after initial platinum-based doublet.
The conclusion of this study was that maintenance therapy with pemetrexed is well tolerated and offers improved progression-free and overall survival compared with placebo in patients with advanced non-small-cell lung cancer 4.
Metastatic cancer lung treatment
The maintenance with pemetrexed was chosen because EGFR was not present, testing ALK was not performed because at the time of diagnosis, the test was not available in Romania. At metastatic cancer lung treatment moment, ALK test determination is taken into consideration because now is possible to be performed in Romania not also ROS1 test and if it will be positive, treatment with ALK metastatic cancer lung treatment is indicated 5,6.
A study by Kalikaki et al. In our case, despite the hpv vaccine dubai EGFR mutation status, patient had a good evolution because he was a nonsmoker and the histology was adenocarcinoma. In the future, if the patient will have progressive disease even if EGFR is not mutated and ALK has not rearrangement, patient can receive erlotinib in the second and third line 9, Immunotherapy could be a therapeutic option taking in consideration the disease evolution and patient performance status, nivolumab registration trial CheckMate or pembrolizumab data from trial KEYNOTElatter requiring testing for PD-L1 expression, being at this moment used for treatment of metastatic NSCLC if evolution metastatic cancer lung treatment after chemotherapy or target therapy 12, Unfortunately, in the long run, resistance to almost all therapies is developed - including in immunotherapy, as suggested by data Case particularities This is a classical case vignette for the switch maintenance with pemetrexed.
Other metastatic cancer lung treatment is that this case confirms the good response of adenocarcinoma to pemetrexed and also better response to treatment for nonsmokers. Our case has demonstrated that association between chemotherapy and radiotherapy is beneficial and in sequential association.
The late, complete hpv ano sintomas 1 year and 8 month from diagnostic is another particularity which should be highlighted. A particularity is also the atypical metastasis discovered on PET-CT metastasis of thyroid lobe and salivary gland.
