EXAM 3 ONC FREI
| FRONT | BACK | NOTES |
|---|---|---|
| ANC formula | WBC x % neutrophils (segs + bands) | |
| Chemop based on ANC | ANC < 1000 NO CHEMO ANC 1500 or more give chemo | |
| Primary ADRs of MGFs (G-CSF and GM-CSFs) | Flue-like symptoms, bone pain, joint pain | Give APAP, NSAIDs, loratadine (histamine mediated bone swelling) |
| Why MGFs | Primary FN - febrile neutropenia prophylaxis, stem cell mobilization, BMT failure, acute FN | Given to prevent FN before it occurs |
| Patient FN risk factors (consider for intermediate and low) | 65 or older on full chemo, persistent neutropenia, bone marrow involvement, large areas of radiation or prior treatment, infection, open wounds, recent surgery, CrCl < 50, bilirubin >2 | |
| FN Risk - Primary prophylaxis | High > 20% - give MGF Intermediate 10-20% - consider risk factors (1 or more consider MGF) Low <10% - consider MGF if 2 or more risk factors | |
| MGF admin rules | Do not use with radiation, Wait at least 24 hours after chemo to admin (24-96) (give neulasta onpro the same day), Cannot use pegfilgastrim or eflapegrastim-xnst if getting weekly chemo, Do not use within 14 days after CAR mod t-cells | |
| Stem cell mobilization | Give GCSF filgrastim daily intil collection complete OR give pegfilgrastim 24 hours after chemo If collection resistant give GMCSF | Peg-grastim or pegfilgastrim are given only once per cycle instead of daily like normal filgratim |
| Secondary Prophylaxis for FN | MGF given to prevent FN or delays casued by it | if previously given MGF for primary prophylaxis, lower dose or change chemo regimen |
| Neutropenia | ANC < 1500 cells/mm3 | |
| Febrile neutropenia | ANC < 500/mm3 or <1000 and falling + oral temp > 38.0 (100.5) for over an hour or > 38.3 (101) a single time | |
| FN Management | Triage - within 15 minutes Antimicrobials - within 1 hour Placement - after 4 hours of observation | |
| Triage of Patient | Site specific history and physical, CBC, test electrolytes, liver/renal function (gen. workup) 2 sets of blood cultures from each lumen of existing central line and a peripheral line site if present 2 blood cultures And site specific cultures | Antibiotics should be given within one hour of triage (PsA therapy - cefepime, imipenem-cil, meropenem, pip-tazo |
| Placement within 4 hours based on MASCC and CISNE | MASCC score under 21 - inpatient MASCC score 21 or over - refer to CISNE CISNE score 1 or 2 - outpatient CISNE score 3 or more - inpatient | Max MASCC score of 26 CISNE 3 or more is inpatient |
| Treatment of Outpatient FN(Low Risk) PO therapy | Cipro + Amox/clav (if PCN allergic use clindamycin) OR Moxifloxacin | |
| Treatment of High Risk FN | Anti-pseudomonal B-lactam Cefepime (maxipime), imipenem/cilastatin, merropenem, pip/tazo (zosyn) | switch IV to PO if GI can tolerate |
| Antimicrobial additions | MRSA, Skin/Soft Tissue Infection, catheter-related infection, pneumonia, hemodynamic instability, c. diff - add vancomycin VRE: linezolid or dapto ESBLs: carbapenem | |
| Duration of antibiotics | Afebrile for 48 horus + ANC > 500/mm3 - may consider stopping Afebrile but ANC < 500/mm3 - stop after 5-7 days Febrile - Reassess causes, ANC does not matter | If cause is known narrow therapy and treat specifically |
| Persistent fever | No change -continue antibiotics, consider stopping additions Cancer progression IF inadequate response after 5 days with antibacterial coverage, add anti-fungal and consider therapy change | |
| Antifungal therapy | Candida can appear after 1 week Aspergillus may appear after 2-3 weeks Only given after 5 days of inadequate response to antimicrobials | Risk factors: Hematological malignancies, cytotoxic chemotherapy, agents that cause mucosal injury, prolonged neutropenia, broad spectrum antibiotics |
| When to use MGF in Neutropenia | Only continue or give MGF if pts developed FN while already on MGF | MGF can be used if pt has any 1 of the following: sepsis syndrome, age >65 yo, ANC < 100, duration of neutropenia expected to be >10 days, pneumonia or infection, invasive fungal infection, hospitalization at time of fever, or prior episode of FN |
| Thrombocytopenia | Platelet count < 150/mm3 or relative thrombocytopenia (50% decrease in plt) | |
| Meds that can cause Thrombocytopenia | Quinine/quinidine Sulfonamide antibiotics Vancomycin Penicillin Carbamazepine Rifampin Heparin Abciximab (GPIIb/IIIa inhibitors) NSAIDs H2 antagonists Chemotherapy Valproic acid | |
| Treatment for medication induced thrombocytopenia (most common cause) | stop offending medication, monitor, CBC daily or more, transfuse plts if < 10,000 | |
| Immune trombocytopenia purpura (ITP) | PLt < 100k and cause unknown, normal RBC and WBC | new - under 3 months persistent - 3-12 months chronic - longer than 12 months |
| ITP management | 1st line ITP Prednisone, dexamethasone, IVIG transfusion under 10k plt | Active bleeding: steroids and IVIG, transfusion, consider splenectomy |
| Refractory ITP | Rituximab QW for 4 weeks, repeat if necessary | Hep-B reactivation test for hep b |
| Chemo induced thrombocytopenia (CIT) | PLt < 100K no chemo, over 150k give chemo | Treatment: transfusion if plt < 10 K Chemo dose reduction or delay ROMIPLOSTIM - only TPO used in CIT |
| Breast cancer prevention based on 5-year IBC risk | Low risk: <3% no intervention High risk 35 or over and over 10 year life expectancy - splint into post menopausal and pre/perimenopausal | pre/perimenopausal - tamoxifen postmenopausal - raloxifene (prevention only) , tamoxifen (2D6) (raloxifene and tamoxifen can cause endometrial hyperplasia, VTE and cataracts), aromatase inhibitors (can cause arthralgia/myalgias/fatigue |
| Types of breast cancer | HR+ (ER/PR +) most common best prognosis Her2+ - worse prognosis but predicts response to Her2 treatment Her2 low Triple negative (ER/PR/HER2 negative) | |
| Breast cancer characteristics to consider | HR/PR status, HER@ status, size of cancer, # of lymph nodes with cancer, metastatic status (incurable) | take everyones titties off |
| Treatments for curable (stage 1-3) breast cancer | Surgery mastectomy (full titty) or lumpectomy (mass) + breast tissue rad Radiation - if given lumpectomy give breast rad, if lymph node + give axillary rad HR+ = endocrine therapy HER2+ = trastuzumab therapy TNBC = chemo +/- pembrolizumab | rad usually after chemo, not given at the same time as hormone therapy |
| Adjuvant/neoadjuvant therapies for aggressive breast cancer | Chemotherapy, ET, Trastuzumab/Pertuzumab, PARPi, CDKi 4/6, Chemotherapy, T-DM1, PARPi, CDKi 4/6, Immunotherapy, Others | |
| Management of triple negative breast cancer | LN + chemotherapy (AC-doxorubicin/cyclophosphamide OR TC-docetaxel/cyclophosphamide) and olaparib if BCRAm+ + pre/post operative pembrolizumab LN - further broken down based on tumor size | 0.5cm or lower, no therapy 0.6-1 cm - chemotherapy and olaparib if BCRAm+ over 1 cm - chemotherapy and olaparib if BCRAm+ |
| irAEs (ADRs from pembrolizumab) | skin, GI, endocrine If experience symptoms start steroids and stop immunotherapy | |
| Management of HER+ and HR+ EBC | LN + chemo with trastuzumab + pertuzumab and ET | LN - less than 0.5 cm consider ET OR consider ET + chemo + trastuzumab 0.6-1cm - ET OR ET + chemo + trastuzumab over 1 cm ET + chemo + trastuzumab +/- pertuzumab (for T2/T3) |
| HER2+ but HR - (NO endocrine therapy ET because HR negative) | LN + chemo with trastuzumab + pertuzumab | LN - less than 0.5 cm consider chemo + trastuzumab 0.6-1cm - chemo + trastuzumab over chemo + trastuzumab +/- pertuzumab (T2/T3) |
| HER2+ | 1 year of trastuzumab or 14 cycles or ado/fam +/- pertuzumab + taxane | do not take either with anthracyclines |
| HR+ and HER2 - | LN + 4 or over - Chemo, then ET +/- ovarian ablation, consider CDK4/6i LN + less than 4 r tumor > 0.5 cm - consider gene expression assay Tumor less than 0.5 cm and LN- - consider adjuvant ET | only difference in pre menopause and postmenopause treatment is there is NO ovarian ablation i postmenopausal |
| 21-gene expression assay result interpretation | 26 or over is pre/post menopause are given chemo, below 26 no chemo | |
| ADRs of treatments | Doxorubicin - cardiomyopathy cyclophosphamide - hemorrhagic cystitis Paclitaxel - neuropathy Carboplatin - myelosuppression Pembrolizumab - immune mediated toxicites | |
| Hormonal therapy | Post - aromatase inhibitors Pre - tamoxifen or tamoxifen + ovarian suppression or aromatase inhibitor + ovarian suppression | minimum use of 5 years but can do up to 10 years |
